I think you should set one up and shoot it. I've had short bows (32")with tall brace heights (9 3/8")and long bows (38")with short brace heights (6 3/8"). All bows had the same cam system on them so that was not at issueand set to the same draw length and weight. In all cases the longer ATA bow was easier to achieve better accuracy.

Now you're talking about a short ATA bow and a short brace height. Just my opinion, but this sounds like a combination fordisaster unless you're next to being a pro shooter or don't plan on shooting anything over 25 yards.
