Jim I think you missed Marks point. It is not that he too lazy to design a new spar for some other guy. Heck just look at his web site to see what he has done for us. Instead he is busy with his own project and his spars are done. If you or anyone else wants to undertake a redesign of the spar, go at it. Mark was good enough to point you in the right direction.
