It's all relevant, IMHO to the shooters body. Generally speaking, a higher brace height will give you a more forgiving bow. The longer your ATA the more stable the bow is. For me being 5'10'' and with a 27" DL I like a bow in the 32-34" ATA and above 7" Brace height.
The higher the brace height, the more "forgiving" a bow is. Basically this is because the arrow isn't on the string as long, making it less susceptible to torque.
Also, if you look at high level archers, MOST of them are shooting something in the 300-310fps range, something with 7" plus braceheights, and some LONG axle-to-axles in the 36+" range. This is one of those subject that gets funny because you'll hear guys say my supernova fastest bow in the world is the best most accurate bow I've ever shot, when in reality, it's probably the LEAST accurate bow they've ever shot, especially when the axle to axle is in the 32" or shorter range. Axle to axle makes a bit of a difference, but that difference is change a little by parallel limb bows. Almost to the extent that you need to look at riser lengths when looking at parallel limbed bows. For me personally, I think my original Trykon XL has probably been the most accurate bow I've shot in my hands, my AM-35 with the Z3 cams is probably a close second, followed by my std. AM35, but I've never really delved into shooting Target bows. My nephew has a 2005 Hoyt Ultratec w/ a 40" ata, and he shoots it great. But I bought that bow specifically for him because I knew it would be pretty forgiving. Past 35 yds, it's so slow that he's a little sloppy, but out to 35yds. he's capable of 4" groups pretty easily, with either BH's or FP's.
Thanks for the feed back guys, I just wanted to confirm things I already thought were true and maybe find any other elements that contribute to better accuracy. I'm thinking of my next bow and I'm wanting something with a 34 Axel to Axel with a 7+ brace hieght. The bow I shoot now doesnt go 7 and the more I think about this when I shoot and see the outcome of some shots I take the more I know I can attribute this to hand torque, want to get rid of that. I'm looking at the Mission VXT for now, it's interesting what Ohbowhunter is saying about the parallel limbs and there length, I havn't really giving this much consideration. Something more to learn about but I'm thinking longer parallel limbs equal greater brace height equals less shooter error...not so sure though. anyway thanks for the feedback:D
Sean, That Monster is EXACTLY one of the bows I was talking about that leave a bit to be desired d/t their excessive speed, short axle-to-axle, and short braceheight. Here is a very good article on bow selection, and it explains a lot of things that many guys should read before they go run out and buy a new bow..... http://www.huntersfriend.com/bowselection.htm Enjoy....
