I'm 6'5". And yes that argument has merit with most things, but with archery, the human body is FAR from a perfect design and very few are the same. In other words...folks goof! To have a design that requires perfect follow-through is stupid. Very few can accomplish it even with tons of practice. At my age, achieving excellent follow-though is difficult at best, dang near impossible for usual. Hence part of the reason I switched to drop away rests. Once you get one dialed in, it can improve your performance level quite a bit if you are having follow-through difficulties.
I was getting to where I could barely score a 465 on a 50 target shoot. Had a couple friends video me shooting. Took a long close look at the whole thing and discovered some pretty big differences from earlier films. My bow arm was dropping a bit early on release, my wrist positioning was nowhere near as flexed as it used to be, my stance had closed in some, my string arm wasn't dropping straight back as it used to, just all kinds of tiny things that most wouldn't notice but when added together was making me shoot a good percentage worse than in times before. My first drop away solved about 85% of the problems. The other 15% I just had to get my dang mind right and make my body work in unison with the bow.
