I checked out the voodoo floss. Looks neat. I think the sleeves are more a general preventative measure rather then a re-hab one. (although I feel they have helped me heal up overuse injuries). Also the sleeves are something you can wear daily and for as long as you want.
If you are interested in a good (and cheap) pair, for either knees or elbows, they are only 24$ a pair from liftinglarge.com. (good fast service too). I had first bought Inzer xt sleeves for $60+ but I dont like them at all. WAY too restrictive for me. With the crusher, just size them by measuring the circumference of the joint they are going over.
I think I am going to order some voodoo floss as well. Looks like a nice tool to have at one's disposal.
