RE: Axle to Axle length and Brace Height?
What works better for some, hinders others.
I have a Martin Firecat XRG. Something like 44" ATA round wheels (excentrics), and a big brace. One of the best target bows ever.
Oddly enough, I have shot my best scores with my newer Stealth Force. Still a long (by todays standards) 39" ATA, and a 7" brace. But it has a MUCH smaller valley, and a SOLID back wall. For the way I shoot (BT with a Chappy Boss) I just shoot better with the Alpine. While it may sadden some to see such a legendary bow beaten by a new "toy" that's life. For now, the Firecat has become my fishing bow.
The accuracy I can get with my Alpine is better than I get with the Firecat...plain and simple. The fact that it shoots the same arrows about 55 fps faster (with 1" shorter draw) is mearly a bonus.
