Leatherface is right. Repping the #1 is only going to get you more reps on the #1. Do some holds and negatives with the #2 (or even the #3 if you're ambitious).
Not only do I do that, but when I've had enough of the #2, I'll move down to the #1 and even the Trainer sometimes and do the same thing, until my hands are swolen and exhausted. Then at the next workout I'll keep it light and do some high volume with the T or #1.
I've also got a clamp to work on pinching a little and I just bought a standard (non olympic) dumbell bar where I load 5 or 10lbs on one end and do alot of different movements to strengthen my wrists. (I believe Ironmind calls this a Hammer?)
I bought the T, 1, and 2 in August or so and could only close the #1 for a few when I started. I just got the #2 closed, but I'm giving myself a full year to hit the #3.
