Terry you subtly hit on the other factor and that is cosmetics. For some reason the half helmet represented the Harley image and the FF is for crotch rockets. I do wonder if helmet choice is not influenced by rider age or maturity with most of our members being in the more aged, affluent and educated and that may place safety above cool. 
There is some truth to that. Where I live, most of the people riding Harley type bikes (that includes Jap bike wannabes) wear half helmets, or even the skull cap (tupperware bowls) type, while nearly every crotch rocket rider has a FF on. For the crotch rocket riders, it's probably not only the "look" that they are after, but also the fact that you're not getting much wind protection on those bikes, as your head is generally hanging out over the gas tank. Demographics would probably support the assumption that most CVO owners are older, with more disposable income...that being a generalization, of course. I certainly fit into the "older" catagory. My reason for a FF helmet is pretty simple: I get this visual of my face impacting either another vehicle or the pavement, and it's not a pleasant visual. Not only am I vain enough not to want half my face torn off or disfigured, I don't heal as fast as I used to, so don't want to take any more chances than are necessary in riding a bike when it comes to gear. Skin grafts or rebuilding my nose and chin is just not something I want to even think about having done. If I could stand it, I'd wear leather chaps and a leather jacket year 'round, but summer temps just don't allow that where I live. 40-80 degrees are my favorite riding temps, 'cause it allows me to wear all my good gear. When I was 22 years old and immortal

, I didn't think about this kind of stuff, but being 59 now, I'd like to maintain my mobility for as long as possible...and what looks I have left. I actually cringe every time I see someone riding with shorts, improper foot gear, etc.
