I have a friend that has/had a hydro XT. I think he likes it a lot... I'm just more into the full harnesses. I've got an Equipe and LOVE LOVE LOVE it! I'm going to need a new one soon and am not sure what to replace it with. It has GREAT back support, you don't even know your hanging in it.

I have to say that I might be the only person in the world that does not like the worrell harness. I wore one for two days in the worrell and had to switch to my equipe. It seriuosly hurt me on the sides of my thighs.
