I have one of the gun clubs from the worsted alsport, the pattern and finish are nice, but the cloth is definitely nothing close to the heavier real tweeds out there. All in all it is a great fall/spring sport jacket.
My experience with Hallak was horrible, they refunded, but still horrible. They essentially removed the buttons off a DB jacket without asking yet they charged me for this. The main issue was that they didn't sew them back on in the right place, and also forgot to sew the interior buttons back on, so basically I couldn't close the jacket. The main stain was removed though I had to send the jacket back to the tailor to "recalibrate"
What is this obsession with tonik? Its not as good as the old stuff, and there are so many better warm-weather alternatives out there such as tropicals and frescos. Mohair also tends to be shiny, something I rather avoid.
Lesser's Navy Hopsack in the 16oz book has a nice finish, and it hangs like steel. Well worth it IMO. If you want patterns, go with Caccioppoli's books, it's very italian, but good cloths with nice hand. I know a lot of people don't like it, but the worsted alsport book from minnis has a few gunclubs in there and a worsted finish so it's much smoother than a very hairy tweed from WBill for example.
