I have the same problem. XXL and the Arai astral fits me best. I also live in an area where not a large selection of helmets are sold. If you are a true rider at heart, you don't miss an opportunity to visit bike shops when you travel. I go out of my way to get to various shops, particularly in large cities. I try on various helmets and make notes of what fits the best. Then when I need one, I can order the right type, size and design. Also, Daytona, Honda Hoot, Americade, Sturgis, etc are great places to try on all sorts of helmets. I never miss many opportunities to try on a helmet.
