Thanks everyone for the feedback.

The amount of travel does pose a problem. In windsurfing rigs, you need lots of leverage for an interactive DH but not lots of range (maybe 40-60 mm). I assumed that one could cascade levers like one could cascade block based systems thereby keeping lever lengths shorter but maybe this gets too complicated.

By the way, how is the DH rigged in Verctorworks Blade? Something similar to your DH Wouter?

Thanks,

Jerry
