I cant remember which CCM pants I have, they do the trick but I might swap them out soon. The Passau is great and I'll always keep it and happily recommend it. The Vaughn was nice and light and with the pro pack did a pretty solid job, I caught some weird shots straight on with it and I decided to go back to the Passau where I feel it was a great balance of everything.
Before my knee setup was just taping the free knee guards you get with G4's to my underarmor pants. I might switch back to the garter belt and the larger ones now that the pad wont get caught up as much. With the smaller Sr. level knee guards tape seems fine but with the larger Pro ones it'd give on occasion. I dont wear socks either so that might be part of the problem.
