Edwin,
I ran some flat carbon down the horizontal stab from front to the rear. Another Tensor owner used some extra depron and made a V-brace. It eliminated all twist and would be the way I would go if I were to do another.
Tylerman,
I think that 8x4 might be the ticket

. I love my Yak. I am running the 26T in it at the moment. Good power and excellent performer.
