I have a Shoei and I love it. Not sure of yours b/c I have never tried one on. Why, you thinking of getting a new one or what. I would say the best idea would be to try the others on before you buy them, see what you like. Good luck.... :arsenal ( I had to use that icon, it's new!!)
I own two Shoei's, I've tried an Arai and Love it. If you get a chance to go to a Motorcycle show do so. Arai usually has a rep there that will tell the in's and out's about head gear and suggested a certain model Arai for your head. I've never tried a Suomy but I hear good things about them and they look SWEET. :clap:
I have worn just about every brand of helmet and the arai and the OGK are pretty much the best out there. I like the OGK more because it feels lighter and the face shields are more easly removed and replaced.
