Be aware of this bar!! The chicken loop has a habit of disconnecting from the harness hook. The release is very difficult to release under load. The slide stopper smashes apart if bar hits it.
Myself and a mate purchased one each and have both had these problems. The bar is hard on the hands after long use. On the + side lines are nice and waxy.
I use the gp bar, I gather they arnt too different. I agree it is harsh on the hands. Other then that I think it's OK. The thing I don't like is how hard it is to remove the donkey dick
