Quick question about the new derlin pistons in the 2013 NT1. If i wanted a stiffer dampening, would i use the 1.1 (3hole) or the 1.3 (3hole)? My mind is saying the 1.3 b/c of thickness, since surface area is the same on the face of the piston but i am not sure. Wouldn't the thickness of the piston create more resistance with the shock oil? I couldn't find anything in the kit or online which shared this info. Any advice would be appreciated, thanks

EDIT:: Answered by a fellow team driver. The 1.1/1.2/1.3 refers to the size of the holes in the piston, NOT the thickness of the piston. I feel like an idiot now...lol
