They take a lot of pressure off the side. Those dang geckos have really long spikes on the "American" gaffs. As I recall, it is only 3/4" shorter (offset), but that does make a bit of difference.
If your knees are giving you trouble, shorter gaffs might not be enough relief. I had trouble with my ankle strength, and then they toughened up and I have not had any more problems. In my experience, knees get bad...and then stay that way.
oh heck yeah! ive got some bad rugby injured knees so i need all the comfort i can get!
