I will be talking to Michael shortly about product testing and the possibility of Distribution. I want to test them thoroughly; although I think it's a no brainer. The big thing, right now is cost affectiveness.

I think a carbon fiber outer coupled with a Titanium inner would be great, as carbon fiber won't work on the twisting torque required of the inner; the set screw would shear it.

A tightly fitted carbon fiber sleeve on the outer shaft or the carbon fiber outer shaft itself would hold true! It would depend on how easily the lower gear is to remove.
