For hunting I think it's main purpose is to quiet the bow, deaden some handshock and MAINLY to balance the bow. Length doesn't matter really except for convenience in a hunting situation. Like my new Guardian. There really is no hand shock but the bow is NOT balanced by itself. Different sights and all that change what you might put on it. I really thought I should have a 7 oz one. 6 was too light and 8 too heavy... but, I went with one close to 8 because he was out of 7 oz at the time. LOL I also like to get one that will fit in my bow case on the bow so I don't have to take it off and on all the time. I went with this Wild Thing... purely for balance and shortness. You'll find Rob and a lot of folks that shoot a lot of tournaments and 3D will go with the longer for balance and added accuracy. A sliver here or there usually doesn't matter in the woods like it does on a 12 ring.LOL I couldn't stand to have a long one myself.
IMO stabilizers on a hunting rig are WAY overrated.
I have to disagree with that a lot. The balance of the bow effects accuracy and steadiness.
