I am in the same boat as Duk far from an expert. I have used nothing but the buscuit since I started bow hunting and I love it for the exact reason you stated. No chance of it falling off. I did notice however the fletching starts to what I call wave a little after a few hundred shots.
Stevie, get one. I lose/bust arrows way sooner than the bristles warp my fletching. For me, it's been super accurate. Just lube it or whatever to make it quieter. Good luck man.
If you really really really care about not holding your arrow you have a couple options:
1 - biscuit
2 - adjust/bend your arrow rest to just 'squeeze' your arrow. This won't be as duarable as the biscuit.
I had a biscuit for 5 years, only reason I move to a drop away because the biscuit is too loud when you draw (spooked a couple deer). I replaced more fletching due to tight groupings than biscuit wear in that 5 years so unless you are shooting 40 arrows / day / 365 days / year then it should not be a problem.
Biscuit was great for accuracy and durability as well. Rain and cold affected it a bit but nothing to really worry about.
