If you use the MK bellcrank DO NOT use stand offs from the control horns when using a ball link. This just adds to the leverage and twist on the control horn. Otherwise they are a pretty stiff setup when using the c.f rods and titanium ends. Also pricer then the pushrod setup or pull/pull.

I have tried the double .070 c.f pushrod on my latest setup and so far so good. Very light and I think it eliminates and variable like the pushrod flexing at the "Y". However like Chip said a good pushrod setup is about as good as any.

I know a a fellow who recently had problems breaking his stab at the center joint. He was flying a pull/pull setup and the control horn was not directley over the hinge line. It was set ahead of the hingeline causing the lines to tighten as the surface was moved. He broke the stab twice before someone discovered this and then the after the fix his servo rail failed(from previous stressing I assume) and ended up re-kitting the airplane. So there are some important thingsin a pull/pull system that need to be followed. A pushrod eliminates those possible conditions. Only thing about a pull/pull I like thought is the small adjustment settings one can make with it.
