I am in need of the wintec (or other similar saddle brand) knee rolls/blocks. I have been having a heck of a time finding them, and when I do most places want my first born child for them. I currently have one of the medium size ones so if you have just one random knee block laying around I would gladly take it off your hands. I will take a pair too of course. I have some stuff that I would be willing to trade for them as well.
