You are definitely right Jaka about minimizing the effects of gear slop, which I honestly had not thought about until you gave your explanation above. What I was addressing, and I think pylonracr was too, is connector slop cause by clevises and Z bends. The most slop free setup possible would be snug fitting ball links on both ends of the pushrod with the horn in the closest servo arm hole and then moved out as far as possible on the control surface. That's assuming extra stiff linkages too. But for those who want to go with a Z bend and plastic clevises, I think connector slop is a bigger concern than gear slop and so going for the most pushrod movement would be better.
