To Joe's point, I have always felt that the grips need more grip, i.e. not the smooth surface they have. Sure the grip extension allows you to get your hand around more of the mass, but still the knob being smooth? no finger notches? As I stated in a previous post, sometimes I really wonder who Arca is taking to when they design some of their stuff. It needs to be more than a unique material, it needs to have function also. You are using it told hold a very expensive camera/back/and lens. Finger notches on the upwards handle are a great idea, yes like the ones Cambo has. I also wish that Arca would make handle for the left side. I am right handed, and thus need that hand for other things it would be so nice to have a grip made that fits in the place of the other non-existing e modules (at least for now). The issue of the no left grip was a big deal for me but I still preferred Arca's focus methodology so I stayed with them.
