RE: consitintaly peep site tube breaking!
Okay I'm on the other hand of usingpeep tubing - I have tried taking mine off and it made some minor difference in noise and the peep does somewhat come back straight most of the time even with a new great string and cable combo. BUT sometimes it doesn't.
I put it back on but have it very longand tied higher than my peep. If it does break off it breaks usually at the nipple on the back of the peep. When it's longer you have enough still there to slide it on and continue your practise or hunting. I have played around with different materials of tubing and the latex type seems longer lasting and faster but the silicone is quieter and a bit slower. Use it. At the speeds these bows shoot you can't beat the sound from one ofany bowgoing off and the reaction to it of a deer or any big game.
