Every time I try a regular peep it's always such a pain in the neck keeping it aligned I always go back to one w/ rubber tubing

Same here. No matter how often I shoot, the non-tube alligned peeps always seem to not be fully rotated when I draw on game-last year I actually spent time on stand twisting it myself when ever a deer approached-to ensure it was properly alligned-I've gone back to the tube alligned site

Do you put a knot above and below and tie the peep on?

Yes there are. It was installed by Tommy at Simon Peter. I've taken it back there to have it adjusted because of teh coinstant rotation problem-the adjustment helped but did not eliminate the problem-so I went back to the tube aligned peep
