RE: Brace height question
Mike.
In theory the rest has dropped when most torquing happens.
On most fallaway rests the arrow is only in contact with the rest for about 2" then it should be out of the way.
The main problem people come up against with short brace bows is wrist slap but what a lot tend to over look is the fact that along with the low brace they are also shooting a draw lenght that is too long and are forced to lock their elbow.
The trick is to get the proper draw lenght so you are shooting with a slight bend in the elbow thus taking the string away from your fore arm.
Keep a loose grip all the way through the follow through and let the bow roll forward that should stop a lot of the death grip induced torque.
I have found with proper draw lenght and form there is no real big difference from shooting a 5 5/8" and a 7 7/8" brace bow.
