I'm stuck between buying either two CoC grippers (probably a trainer and then a No. 1) or "the vise gripper" that t-nation recently said was a good buy for grip training. As far as I can tell: Pros of CoC: reliable and I know it will work Cons: non-adjustable Pros of Vise Gripper: adjustable, so I don't have to buy a new gripper later on Cons: not sure if it works as promised or is reliable. I read that it has a shorter ROM than most grippers so I'm not sure if that's a huge problem or not. Anybody have any bad experiences with the vise gripper? As for my current grip strength I've done 325 x 5 double overhand deads, 225 x 12+ double overhand RDLs, and 400+ deads for reps with mixed grip and no problems.
