This is Motostrano Joe's question, I want to be respectful and not hijack it. But I do have something that may help you gentlemen. I tried the FX18 a while back (at a Parts Showcase) and it had a greatly improved fit. I compared it to the FX37 directly, and did not notice the forehead pressure that (37) had. The AFX rep was emphatic that this issue was going to be cured on the FX-39, and that it woudl fit similar to the FX18 I tried. I feel he was accurate and sincere.
Everything I have heard indicates that the FX-39 will be a better fitting helmet. I do not feel you will have issues with it.
