Hoosegow, I think you would do better asking at http://www.goheavy.com/forums/train/
The reason I'm pointing you over there is that there are so many different knee wraps out on the market, you could get lost in all the names. Also, this board is almost exclusively powerlifers and they know which wrap works best for described problem areas.
Just an oh, by the way, 365X6 is pretty darn respectable. I've done 420 as a single, at 148, but that was 20 years ago, and I haven't gone over 245 for reps in close to 6 years.
