Im gonna buy a CoC gripper too and I was debating if I should get a #2 also. I met someone on youtube...who is a St. Wilhelms member...00056. He gave me some advice. ill quote his comment here. It made me think about getting the #1 to do more exercises rather than just sticking with the #2 and still increase grip strength. Take it for what its worth.

If your not strapped for cash then I would get the T, #1 and POSSIBLY the #2. Even IF you can close the #2 it will most likely be a max effort attempt. And you cant just keep maxing out on any kind of exercise, and grippers are no exception. I would still recommend getting the #1. Even if you do close it there is a lot of exercises you can do with it to get stronger. For example, 3 finger closes, 2 fingers, inverted closes, you can file the inside of the handles, Overcrushes, strapholds etc... None of those need to be done when your first starting out though, take at least a few months for your hands and tendons to get use to the pressure.
I have been doing grip training for a little over 2 years now. About 6 of those months my hands have been injured from grippers. I tried to go to fast to soon and paid the price. TAKE YOUR TIME, DON'T WORKOUT WITH THEM EVERYDAY AND DON'T MAX OUT EVERY TIME. I had a horrible case of tendinitis and could not pick up a book or turn a doorknob without my hands being in horrible pain. And im not an old man, I was 19 at the time.
