Helmet manufactures usually only work from a few molds. Which ever mold fits yer head (oval,round,pineapple shape,LOL) is the way to go. Shoei for me,20+ years. RF1200 last few seasons. Wear what fits and is the most comfortable,everything else matters not. Of course Snell or DOT is a good feature, mmmm...or is it?
Brain doctor specialist who worked on me thought perhaps my choice of lids was a contributing factor to my brain injury. He thought perhaps my lid was TOO HARD,TOO WELL MADE. His theory: Helmet manufacturers make their helmets to overcome rediculas specs and expectations. They drop them from 50 stories up,drive over them with an' 18-wheeler,set fire to them...kiddin'.
Are you better off in a head on collision in a giant 1950 Cadillac with a giant steel frame that doesn't budge on impact...or a new Toyota with "crumple zones." Are helmets too hard? Is transferring all of that bad energy from impact directly to your brain a good thing?
Did my over-engineered helmet contribute to my brain injury?
Read some of my threads/posts and make your own judgement.
