So let me get this clear, The bamboo that protects my arm should be rough to not spoil a shot? The only place my string touches my arm is about 4 inches back from my hand, Meaning that the arrow has already loosed itself from the string. Also, wouldn't a rough material be too abrasive on your string? Isn't tanned Saddle leather also "slick"? Please continue to post on things, but try and not be critical of everything that you comment on. There are a lot of people on this forum that I would take that advice from and run with. You aren't one of them.
