I'll be doing a passaround of two books and the trainer in about a week; I just want to read the books again first. The books are The Grip Masters Manual and Mastery of Hand Strength, both by John Brookfield. I can add you to the list if you'd like; Bobwhite also indicated interest so he's on there too. I'd guess that at that level of reps on easy grippers you can probably train on a #1, but the trainer should give you a good indication of where you're at now. I've run into several people who couldn't close the trainer, and so far only three who could close the #1 right off. For reference, I can do about 20 full reps on the trainer and can close the #1 with both hands. Once. Barely. But I can close it. Try this. Close your easy gripper using only your pinky and ring finger. If you can do this you're probably ready for the #2. These books are great though; it really gives you a new perspective on training your grip.
