I was looking at those Fox Enduro pads in a shop the other weekend. They do look very nice but have very little padding and it kind of put me off them. I have been struggling to find pads too. POC are great but have been between sizes with them a bit and suffered. I may try a medium set in the Joint Knee but only if I can find is as a bargain somewhere.
I currently alternate between Kyle Straits and Fox Launch, both are great and frequently go through the wash!
I am interested in the new Raceface ambush pads too, people do seen to like them and they will go on without taking your shoes off, which can only be a good thing.
