If you have concerns about the power or performance of the 775 pro you can easily use the same system with a mini-cim.
What size pulley are you using on that?

However the mini-cim is not a 1:1 replacement for the 775pro, although the 775pro is about 125 watts more powerful than a mini-cim the main difference is output speed the Mini-cim rotates at around 6000rpm vs the 775pro which rotates at around 19300rpm so about 3 times as fast, this means that if you were to use a mini-cim you wouldn't require such a large gear-reduction( but also take into account that the mini-cim outputs less torque vs 775pro geared to the same speed as the mini-cim)
