RE: Peep...With Or Without Rubber Tubing?
If you don't want to use a peep with tubing AND you don't like worrying about the peep rotating correctly each time, try a "TRU Speednok with Peep Aligner". This is a nocking point that screws together to pinch onto your string in place of a crimped nocking point. It has a little tab that sticks down on the back side of the string. Each time you nock an arrow, the arrow nock hits the tab and turns your string perfectly each and every time. I had one on my old bow and loved it. It never moved or caused me any trouble whatsoever. As the string stretched I just moved it slightly to compensate. With today's string materials this won't be an issue after the first 100 shots or so.
As far as peeps, you can't beat the Fletcher Tru Peep.
Good luck ... Shockwave
