Earlier this year I bought an Arai Signet-Q, which is designed for a narrow, "long oval" shaped head. Fits snug and nice, much less wind noise than my HJC and the time unti I get that piercing hotspot pain in my forehead has been about doubled (1.5 hours from 45 minutes). I traded out the 7mm liner for a 5mm (their thinnest) and that helped as well.
