of the ones u listed, id go for a shoei.. rf1100... its gotten good reviews, and has one of the best airflows without being overly noisey
with RE to the scorpions.. my exo400 is SO noisey i cant stand it... but it DOES have a bronze visor no one else makes... so i love it too.. grumble grumble. turn my head right and it whistles SO loud, turn it left and the general wind noise seems to double.
ugh
i like a lot of the icon helmet styles
the rubatone paint is nice, its a flat rubbery feel, im not a GLOSSY fan really
the liners also feel the comfiest to me
but id go for what fits best... or... the top 3 best fitting.. and then narrow it down by wind noise and venting ability and style after the fitting
