Keep a good eye on your peep tubing. The shop I work at tried some of that new silicone stuff and had alot of problems with it slipping off the posts and it snapping the shooter in the face. Yeah it has a 2 year waranty but if it slips off the post every few shots what use is it. We have since stopped using it and have gone back to the old type of peep tubing. Yes the old stuff dry rots but if you keep an eye on it and replace it. You'll be in good shape. Also just tye some of that dental floss above and below and put a drop of glue on each knot above and below and it will be ok.
