Tried the JT Skinz kneepads, ripped the spandex part the first day playing. Guess they weren't designed with non-aerodynamic backmen in mind
Got some Dye kneepads, havent' had a problem with 'em.
Just got a new pair of the Dye Slider shorts. Still love 'em. The 2003s have better venting so they're a bit cooler. Othewise about the same. I found they fit better if you go down a size from what you usually wear (L instead of XL in my case)
Robinator - I have the same problem. The cup is placed above the crotch, so it doesn't cover all the equipment .
I replaced the foam cup with a hard cup. Can't be too careful down there
