That's odd... because this is what I got back from Never Summer in an email
Yeah I know what they say, and it may be true because of the carbonium. But the dampening is on another level above the Proto from everything that is written.
Even BA called it the SL/Legacy on crack.
Dampening and Flex are both 5, on both SL/Legacy and Cobra/X. That's why I make that comparison.
I see the Proto as a souped up Evo. Same dampening, same shape, both twins etc.
