RE: Quiet CBs
 

My arrow makes more noise hitting the target at 30 yards than my Excal does firing it.
Outside of game there are other benifits to dampening the whole system, I shoot a whole lot and that noise gets on my nerves after a while. Sorta like someone slamming the door on your new car.
I think the neatest part was Don's ability to find the harmonics of a string and counter it with whiskers. The bow has always been a pleasure to shoot, losing that "crack" sound (and feel) makes repetitive shooting more enjoyable.
