Quick help with spread collars

For my next CottonWork order I want to get the ball rolling in my wardrobe with standard spread collar poplin dress shirts of an English persuasion (not Italian), to be worn mostly open collar at this time, but prospectively with ties as well. Choosing the perfect collar is what I need help with.

Here's what I'm after:





With CottonWork's offerings, the closest collars to what I want I think would be the Spread and Wide Spread:



According to CottonWork, the Spread has a point length of 2.75" and a spread of 4.25", while the Wide Spread has a point length of 3" and a spread of 6". For comparison, their Buttondown has a 3" point and a 3.75" spread which, strangely, doesn't seem strikingly different to the Spread.

I've ruled out their Ainsley collar due to its outwardly arching points, as I'd prefer a collar that's cut straight. Supposedly, it has a 3" point and 4" spread, though it looks wider than the Spread.

Why don't you take measurements of an ideal placement, and then have them make that sort of collar for you? I've been able to do this with MyTailor with nice results (they even made a collar for me based on pictures of another shirt, and it came out quite well).
