Well I'm in the market for a new helmet and I've decided I want to go with one of the modular ones. Right now my helmet of choice is the Nolan N102, the reviews have been excellent, the price is good, and it comes in blazing yellow which I like. The problem is that nowhere around me carries Nolan so I can't try one on. Any idea how these fit in relation to HJC or ICON? Right now I wear a size large in both of the mentioned helmets but I just don't know. I really hate to order one in and not have it fit right.
