I'm using the Dye pads and they're great. They're a little tight, but in the sense that they provide knee support. I feel like mine have broken in and most of the time I don't really notice they're there.
Ill toss my vote in for Eclipse. I used an older dye pair before and was not impressed, not dissapointed but just meh. The eclipse ones are large enough to cover everything and tight enough to not move too much. Best advice has already been given though, tey them on if possible.
I've been using under armor volleyball knee pads for a couple years and they work great... Occasionally slide down but not much... I am going to get a set of dyes this year tho... I like the Velcro aspect to keep them up. Also they provide significantly more coverage than VB pads... Eclipse are nice too!
I have to through in my vote for the eclipse as well, I rocked a few different styles of Empire knee/shin guards and the all fell apart and had mad slippage. I would have to pull them up after every two or three points. I been rocking the eclipse ones for a tourney and a lot of practices and ZERO issues and no signs of wear or tear yet.
That's my 2 cents.
