Bianchi, I have been meaning to tell you this for a couple of days, but it keeps slipping my mind. You have emphasized an interest in stiffness, and yet you have also mentioned an interest in Sapim Super spokes. I just want to make sure you know that they will make an extremely flexible wheel, i.e. ~15% more flexible than a wheel with the same number of C-X Ray spokes. And of course the C-X Rays are already very flexible. You may get what you want from them. There is no way for me to say otherwise, but I wouldn't commit to it without trying them out beforehand. For you to be happy with a spoke like that, I would think you would need at least 28/32.
