I prefer the comfort and ventilation of the Bells better. But my favorite graphic has always been the Nakano replica because the eyeballs are funny to me.
Couple of my favorite ones, I remember them being hard to find though... Funny enough, I've never owned a Suomy, but love the graphics!
HCP Designs is a local guy to us and does a ton of offroad and snowcross helmets. We had him do a helmet for Danny last season and I think it turned out great! Here is one he did for the boss a couple years ago Andrew Swenson is another one that does some really nice work.
Most any Schwantz Replica... and the Screaming Chief!!!! Lots of Suomy goodness out there also... plus one offs like almost anything Rossi does....LOL
