Used to have one, got tired of it. My old Q2 has a small enough grip that the bow just "rattles" in my hand. You don't need a sling to have a surprise release. Best two things I ever did for my shooting a few years back was begin opening both eyes instead of just my right, and shoot at three yards at a big target for literally days until I truly developed a surprise release. Aiming is always my second concern when shooting after focus on release.
