I've been riding my Evolution stripped back to the shell at 3˚ nose down.
I have been experimenting with padding, and I'm going to re-cover it by sticking a thin layer of leather at the back and then re-glueing the cover on. That will effectively make it a Composit with 2mm of extra padding under the sit-bones.
I have an old Forma here that has the same shell as the Composit
The Forma is the same shell shape as the Carbon Lite, Dynamic, Drakon, and 209. The Composit is the same shell as the Carbon, Evo, and Stratos.
