I did get the newer version Rehbrand, 7751 is the model number. I went with basically exactly the right size, in the middle of the range they give you anyway. They fit tightish, but no problems wearing them for the whole squat session.
I LOVE them.

Hack away at anything which isn't essential. Do what you love, and do it often. Fazc.
Everything competes for recovery so more assistance is not always the best idea. miked96
