RE: Question Involving grip tightness.
thenuge, from a shooting form standpoint, it doesn' t matter whether the arrow is on the string or not. What matters is executing good followthrough and not grabbing the handle until the arrow is sticking in the target. If you get into the habit of grabbing the bow' s handle at any time, you WILL begin anticipating the shot and you WILL eventually have serious trouble with accuracy... if you don' t already.
I also agree with goldtip. If your bow is recoiling that bad, then you need to do some experimenting with different stabilizers to tame the beast down.
