Brent,
It's not the quantity, but the quality of opinions that I am interested in. And your quality in my book;)
One of the things I really like about ththe Arai line is not only the ability to replace any or all the innards of their helmets, but you can get a range of sizes in most of the sections to adjust the fit. For example, the medium and large in the Arai line use the same outer shell, it's the difference size replaceable inside sections that determine the head size, and shape. You could probably take a Corsair V and with the right combination of innards make it fit well on a 1yr old gorilla.
I plan on taking a trip over to Philly to the Revzilla headquarters and showroom. I will be able to try on EVERYTHING... to get a feel for the proper fit.
I was more wondering along the lines of brand preference, parts availability, comfort preference (airflow controls, fogging, range of motion). Then there is the old quality to value ratio...
I realize that this could end up as a "What's the best oil?" thread. I can live with that.
