I had been wearing a 3/4 HJC helmet for the past few years. However, I have an upcoming trip from New Jersey to Alaska this summer so I just purchased a Schuberth C3Pro modular helmet for the trip because of the extra level of protection it affords.
I have a Modular Scorpian EXO-900 that is fine until the temps hit around 90 and the chin bar is swapped out for a visor and I'm good for an hour or too. The issue is I was a real idiot and got the cool looking matt black version; its not so cool! When I'm on the road for long runs I have a silver 3/4 Bell that is higlhy vented, very lite by comparison and has a large drop down visor and interior sun visor. I'll ride 8-9 hundred mile in 100+ heat with this helmet comfortably. Rarely do I ride without a lid; when I do its only a few blocks to dry out my helmet and hair while on a long trip or in my very rural neighborhood. One time down without a helmet will convince pretty much anyone that its worn for a purpose - I was very young, very quick in reaction time, in great shape and extremely lucky.
I have a Nolan N104 with a Sena 10R and upgraded iASUS speakers installed.
It's the most comfortable helmet my big head (2XL) has ever worn.
Never again will I have a helmet without a drop-down sun visor... it's the dog's paws!
I love the modular and ride with it open about 60% of the time. Always closed down on the highway though.
Hoosier Daddy, too funny on the "giving us the finger" comment, now that you mention it, it does look that way when you look at the bar graph sideways. I'm surprised that modular helmets lead the pack. I thought it would be full face or 3/4 for Goldwing riders, but I guess that is really what the modular is, a compromise between both of them.
