Picked up a pair of HP45X and Covert QRL to try. Trying them on at home the HP45X fit more snug, almost too tight, and definitely have the better padding but the QRL are more comfortable. Not sure which way I'll go and will give both the on ice test before deciding. Length wise both fall just above mid-knee which will work.
I'm a little disappointed with the legs above the thigh board being thin foam on the HP45X; taking a puck there sucks and I thought they'd at least have a plastic insert. I want to like the QRL more because of how comfy they are, but the padding doesn't seem any better than my retail Tacks girdle.
