Very true, Dan... same concept as our hush kit or string leeches. It HAS to be soft and pliable to be able to soak up the shock and its accompanying vibrations, yet obviously archers want a durable product simulataneously. Finding that "sweet spot" is probably a tough thing for manufacturers to do. I like the idea of having at least one extra stopper around too so that one getting damaged doesn't have the shooter waiting a day or two for a new one to come in. Maybe that's why I've got an extra one in my tackle box, too.
