tubing is loud and dangerous. A bunch of years ago mine broke and came back and hit me right in the eye. Compromising my eyesite is not worth it. I now use a string loop and a winner's choice string. No peep problems whatsoever. Even if you change the tube every year or whatever, how do you know the tube doesn't get nicked or damaged while hunting. Then at full draw POW! that thing breaks. Not for me.
