I much prefer a longer bow also. If the bow is made for your draw, you'll be surprised how close the speed will be..depending on the bow design of course.
I'm used to olympic bows and have hunted all over the US and canda with 66-70" recurves. No problems, its all how you hold your bow. The only time that I have seen a down side to a longer bow is a groundblind. I can shoot my 68" bows out of the nastiest trees and brush you'll find. My 70" did get caught up in the Newfoundland Tundra a few times, a 66" would have been perfect.
I'm 6" with 29"draw if shooting 3 under, 29.5 if split.
The thing I LOVE MOST about a longer bow.....you can hold at your draw a lot longer waiting for that critter to enter your shooting lane than with shorter bows.
My first custom was a 60" Silvertip, and I tried many 58". Started shooting FITA target and saw the light! For me anyway, I know to each their own. Shoot 'em all and pick for yourself!
