RE: What makes a bow stable and shootable?
I've never had a bow that shot better for me than Hoyt's ProVantage series. 46-48" axle to axle, mild cams or energy wheels w/ 50-65% letoff, massive deflexed risers, solid recurved limbs and 10" brace heights.
Lots of guys are shooting well with insanely hard cams, severely reflexed risers and comparatively low brace heights, but they all say the same thing. The bows they shoot will shoot accurately "as long as the shooter's form is good."
How does the bow shoot when your form is NOT good? That's what tells you how stable and shootable a bow is. My old ProVantages suprized the devil out of me, more than once, on the NFAA field archery course, when I knew I jerked, choked, hiccupped or otherwise totally blew a shot on a 65 yarder and still got an X-ring.
