With optimum launch angle and spin 275 is about 110 ~ 115 swing speed. That's very very doable for a young athletic guy, I'm getting on for 47 and I can get her up to 120ish, rarely flush the ball at those speeds though. A throttled back swing at 105ish will get me 240 ~ 250 yards carry. Last year I drove through the green of a 360 yard par 4, hit the front bunker and skipped through the green ended up in the back bunker. From the normal landing area to the green is a pretty steep down hill but the peak of the hill is 260~270 and I flew that easily. Thing was I just wanted to send it down the middle, so I just relaxed and made good contact, I guess not trying to smash the ball at all actually allowed me to swing more freely.

Bear in mind that the lower ball flight isn't gonna land at the same spot... You're likely to get the same total distance unless you're really moon-balling it.

Just a check in. I ended up buying burner 2.0 irons on Saturday and immediately took them out Sunday and shot a 91 which easily could have been an 85 (par 65) which is great for me. I know my swing is still a work in progress as I hit quite a few way behind the ball but I got an extra 10 yards on similar hits than with my old set. The new set is 4-AW and I am actually still using my old 3i but the AW was a welcome addition to my bag.

All this driver talk has left me with some questions. Right now I play a 10.5* loft and I get about 250 carry with minimal roll but I hit moonshots with it regardless of tee height(about same height as 3w). How much extra distance could I reasonably expect by going to a 9.5*.

Research driver heads, 9.5* will help but not cure it. Lower launching shafts, low spin club faces, and using the correct ball all play into it.

Then again, I still hit high...

Get on a launch monitor before changing drivers.

If you are getting minimal roll out it sounds like you are ballooning the ball, you are likely producing too much backspin. High launch angle, low spin is good and produces long carry and good roll out as the ball does not come down at a steep angle. A ballooning ball is bad. Backspin creates lift which to a degree is good but much like an aeroplane with too much lift compared to forward velocity too much causes a stall (don't know if the physics are similar but the result is). Basically the ball balloons up and then drops out of the air.

You want to achieve a more ballistic trajectory, and before getting advice on how to achieve that, (swing/stance/ball position/equipment, etc) you need to know exactly what you are doing at the moment.

Lower lofts become more beneficial as clubhead speed increases, and vice versa.

Very very generally speaking, for an average swing type and ball flight, if you hit it 250, 9.5 is probably about the right loft.

10.5 is appropriate for people who hit it ~225 (which is a lot of people). 8.5 is appropriate for people who hit it 275. 7.5 is appropriate for people who hit it 300.

If you have a lower ball flight than most people, adjust up 1 degree.
If you have a higher ball flight than most people, adjust down 1 degree.

If I catch the fairway, I usually get 275-310 out of a drive with my 8.5, but I should probably switch to a 9.5 because I have a very low ball flight. That said, I use a top-heavy old small titleist driver (~1998), which is designed for a low spin boring (low) flight, and an extra stiff shaft, both of which result in lowness. I used to get away with it better when I played much more and was much stronger. With current enormous drivers, I'd be fine with 8.5.

I also suspect they use "vanity" angles these days (8.5's are probably 9's in reality). Same with shafts.

Aerodynamic stall is caused by excessive alpha (angle of attack) for a given airspeed (or just plain insufficient airspeed), leading to delamination of airflow over the top of the wing. A golf ball is not an aerofoil and therefore does not have an alpha, but it's spining does result in different air pressures on each side of the ball, which can result in the "balloon" flight.

Though, like you said, there are several components that work together to produce that flight, a lower clubface angle will solve the problem regardless of cause, incrementally.

Finally got back into the 70s after about 3 pretty ugly rounds. Shot 79 yesterday. It was certainly one of those "could have been way lower" days as I lipped out 4 putts on the front 9.. Finished birdie-birdie after making a double on a par 4 where I was 40 yards out after my tee shot.

Heading out for another round today. Course has been tough because it's rained so much lately and everything is just staying kind of mushy. I've chunked a lot of chips and wedges recently because of that

nice. i have to take a run at the ball to even hit the fence frown.gif

I think that what everyone is telling about the launch monitor is the best way to do it. In the US it's very easy to find one. Around here we don't have the chance for trying everything. 

 

I have an old Titleist 905R (I love this club) 9.5° with a low torque (2.2°) stiff shaft. I have learned to control my ball flight, but one they a guy from the club I used to play, he is a "club maniac" he changed his clubs as he changes his underwear haha and he had a Titleist 910 8.5° with low torque X-Stiff shaft... the club pro told me to aim for the farthest part of the range cause I was putting the balls on the street laugh.gif. So go ahead and try, you loose nothing.

The issue is more about your swing than the degree loft on your driver. As you say:

Watch the pros swing. Their divots are in front of the ball. They get their hands out in front of the ball at impact. They are hitting down on the ball, not lifting up on it. Here's a picture of Rory:



I drew a red line that represents the angle of the club on a pretty typical swing from an average golfer. Compare that to the angle of Rory's club. You can see how his hands are out front, and he's swinging down on the ball, which delofts the clubhead. On a swing where the hands are not out in front of the ball at impact, the clubhead will have more loft, causing you to hit the ball higher in the air, which will make you lose distance.

It takes a lot of work and practice to get that type of swing, but you'll notice every pro does it. Tommy Gainey, who has a really ugly swing, probably does the best at getting his hands out in front:

Yeah Tommy Gainey has a fugly swing but impressive how he can hit a normal PW 160 yards. I use to play with a friend, that I don't know what he did, but for a 140 yard shot he used his 60°, it was crazy... I'm not kidding, joking or something like that, I saw that a lot of times. His trajectories were very low, so a 5 iron he didn't put it in the air. 

 

From the first pic... salisboss, remember the hip slide? Look at Gainey's left leg... look at this pic of Rory:

Any type of extraordinary distance like that just comes from delofting the club so much at impact that you're essentially clubbing up.

This is what a lot of Super Game Improvement clubs have done to advertise for "MAXIMUM DISTANCE!!!!!". I believe the Burner 2.0 PW is essentially a 9i with regard to loft.

^ This is true across almost all sets these days vs. sets from the 80's and previous
