IF anyone actually saw a slow-mo video of a high performance bow being shot , trust me you'd wonder how the BOW stays together let alone the little rubber squid arms on a silencer!
You should see Sight bars and stuff flexing and vibrating all over the place.[:-]
Violent stuff.

No rubber molded silencer on the market will take unlimited abuse.......Cat Whiskers served to the string and clipped very short are probably the most durable/practical alternative for an in string silencer method.

But like you said........so many accessories and so little time (and cash).

Rubber's cheap, play hard.
