Definitely try to get your mitts on it to get a feel for it. The grips on the cs1 are pretty fat, but you make like that. Also you can trim the CS2 grips to fit on them for a slimmer profile. I had an onslaught and liked the shot of it, but prefer the shot of the gtek. Plus in the back of my mind I know its always going to work. I never had an issue with the onslaught, but always a nagging thought of WHEN will it mess up.
