Sims Decelerator and Cabela's Copperheads?
 

I'd really appreciate any reviews of these products. The decelerator is a little more expensive than other string stoppers. the "break away" technology seems kind of like a gimmick. Copperheads look exactly like a Striker without the scallop in the ferrule. They're on sale for 18 bucks, so I wonder if they're worth a try...
