just picked up a spare clone to use as our back up motor and it has the cl1 cam in it. The rest of our stuff is built with the cl2. What kind of difference is there between the 2. This is mainly going to be our back up motor, but if I have to use it, I would like it to be atleast pretty good. Is it worth it to have it swapped out or will it be atleast comparable to the cl2.
