Just looking to change set up. I hear good things about Curtis Door set up. I don't have any Kyo springs. The stiffest I have are orange Tekno I see the kyo are back ordered at amain. I have some losi springs but they are only 80mm long. I think the silver would be close as it 3.4lb pressure which I think is the same as the orange Kyo?? Any thoughts?? I have the Kyo 8x1.3 pistons and also the tekno pistons 8 x 1.3 the tekno are more concave not sure what difference that makes any comments on that? Thanks
