With the new NLMT tires, what are the thoughts on grooving/siping? How small of blocks, how deep to sipe, etc.? I know that track conditions obviously pay a huge part, but what have people learned to help the new tires work in different conditions (I really am trying to get help with the 3's)? We have had decent luck with the 2's, but are currently running some races that we are required to be on 3's.

3's just like 30's needs lots of sipes. I prefer more sipes and less deep. To be honest you sort of treat it as a harder tire then a 40 as far as sipes go, IMO.
