I feel your pain. I swear I must currently have 20 helmets....full-face, modulars, Harley half and quarter helmets, etc. The absolutely best fitting helmet I have ever owned is an Arai Quantum II. Unfortunately, Arai discontinued that helmet line. I wear Shoei RF 1100 and 1200 helmets....pretty good fit but I have to get thinner cheek pads than those that come with those helmets (33mm). I have a Lazer carbon fiber that is pretty comfy too. I can't wear an HJC or Scorpion. Just can't get them to fit correctly with my round head shape...too many hot spots and pressure points.
