RE: Speed
The really short brace bows will be easier on the wrist than in years past due to the STS but they are still just as touchy.
The speed bows,even the low brace ones will bring about future technology to help us get those kinds of speeds out of higher brace bows in the future,just wait and see.
We were once only getting 330 out of 5 1/2" brace and years before that,even less.
