just bought some of the Nxe pads at Campaign, I found the sizes jumped from size to size so it was hard to get nice and snug, but overall found them very comfortable, non restricting and only wanted to take them off when I was cooling down.
Have used angel pads before, i found them to be a little uncumfortable and difficult to get on and off, and i had to keep readjusting them.
Have got some redz knee pads in small but they dont even fit round my arms so can't comment, but other people rate theirs quite highly, especially as it's rare to find a pair that you dont have to take shoes off.
hope this helped
