CoC gripper question

Comrade grip-freaks,
I recently bought (based on a post here) the Captains of Crush Trainer and #1 gripper. I went to the US recently, and took delivery. Back in India now, I opened them and tested them. I find that the #1 is now my ‘working’ size, and the Trainer gripper is not a challenge.
I requested Ironmind if they could give me a #1.5 in exchange, and they very kindly agreed.
I just thought, "Wait! Why don’t I ask more seasoned people? Is there a way for me to use the Trainer gripper and keep getting a stronger grip?" Maybe I don’t need to return my Trainer?
Shaving down the handle is one thing I can’t think of doing, I must say! The damn things are too pretty to disfigure! ;)
Also, I can’t figure out which is the dog leg in the gripper?
