Due to the different head sizes and configurations some brands may fit you better than others. It's a very personal purchase and one really has to get what works for them. One size surely does not fit all. Good luck with that new Arai. Checking out the different product offerings and doing some consumer research is always a good idea.
So far my SyMax III helmet is working out OK. No buyer's remorse. I was looking for a good helmet at a fair price. . .nothing fancy.
Pros - fit as well as the same size HJC I got in an old open face model I purchased years ago (and still have). Overall good modular helmet. Worth it's price. The chin bar action gives a resounding clunk to let you know you've got it shut all the way. The drop down sun glasses (shade) works really well. . .first setting is fine. . .retracts with the push of a button effortlessly. Venting is certainly adequate.
Nits - the liner truly is easy to remove for cleaning. That being said sometimes I have to reattach the liner along the forehead area after I take the helmet off. . .especially if it's a really hot day (still breaking it in and the pads need time to configure). No big deal. . .it is comfortable. The chin bar can be a bit clunky and you have to make sure you use it correctly but does the job.
One does pay a chunk of change more for a Shoei or Arai quality helmet. . .so at the end of the day it comes down to how much you want to spend and how you define your needs.
