I sent them a list of questions Don. I may end up with a full face, but I am still leaning against it. Although, the discussion came at dinner the other night (yep, you missed a good one) and after talking to Terry a bit on the subject I am falling off the fence a bit.
Duane...using the flip face allows you to flip it up at stoplights, etc to talk to others in the group you are riding with. It's literally a two finger, one hand operation to flip. It look a little goofy to ride with it flipped up, but I do so for short distances, like when you're passing through a small town, or going fairly slow. Also, on the Nolan, the sunshade is very nice and eliminates the need for sunglasses in my case, but that depends to some extent on how that portion of the face shield lines up with where your eyes are set in your head. (Don's head did not allow him to enjoy that feature). I can have the sunshade just one click up from all the way down and find it blocks all but the rising or setting sun, and I am looking through the clear visor. My spectacles are transition lenses, so provide the same benefits as sunglasses.
I also have a HD flip face that I use on the Vrod (no need for the J&M headset built into the Nolan)...think it's the Stealth helmet, but it's built by KBC for HD. It is VERY comfortable, and literally takes only your thumb to flip up, and it is extremely well vented.
If you wear glasses, the flip face helmets are the only way to go for a full face, as you don't have to remove your glasses to put the helmet on/off.
The Turbo Goggles for skiing would not work well, I don't think. They are made for fogging that is encountered when it's 15 degrees outside and you're not moving...the little fan would suck moisture in...and I'm not sure they would fit over glasses. Not many of the ski goggles fit over glasses.
