I would recommend putting the hiller set up on from the Blade CP. It includes the CP grips and linkages. It isn't too expensive and when set up right seems to hover like a CX.

You can't move the inner weights, but all additional weights should be as close to the paddles as possible.

I fly with the plastic blades and have no problems with them. I have hit a piece of plywood before and it only put a small scratch on them. From my experiences it doesn't break anything else that a normal crash would like spindles and main shafts.

To tame the tail a gyro would help out a lot. It seems like the E-Flite gyros are the only ones that work with the CPP. I have heard the G110 and G90 work just fine.
