Have the Nolan 102. Sun visor I often lower to the first click where I don't look through it, but it still blocks the main sun rays since they come from above (kind of like a visor would). they sell a stick on tint that will do the same with a full face helmet for a cheap enough price. It's all I normally ever need in the Northeast.
The flip ups are super convenient putting on the helmet with glasses, they are super convenient stopping for gas. Yes they are convenient to speak on the road to a riding buddy at a stop sign. That's about it, and they are less convenient during the ride due to noise, weight, and overall crash safety.
Otherwise I find no real improvement in convenience from a full face, such as at a rest stop etc. as I always remove my helmet when resting anyway to get a faster recuperation process going.
The Nolan has steel hinges which is important to me over plastic in a crash. That being said, I have read and agree that flip ups are some degree less protective than a full face in a crash.
Combine that with the fact I can live with but don't particularly like the extra weight, and I will be going back to a lighter stronger full face helmet next purchase.
Actually I went back to my old Scorpion 700 for awhile (not a particularly light full face), enjoyed the little bit of weight difference right off. However I got to test the crash resistance of it's chin guard rendering the Scorpion garbage pail fodder. Worked great but I'm back to the Nolan until I purchase a nice new light full face helmet replacement.
As to Scorpion when thumping down on my face. Didn't even feel the thump, very good that way. On the Scorpion downside, it moved about in turbulence on the interstate more than I liked, kind of annoying, (Nolan doesn't). The face shield on the 700 sucked badly in the rain, hard to see through with rain drops and streaks sticking to it like glue (had a heck of a time leading at AQUASTOC with mine (Nolan is decent in the rain). That wouldn't be an issue with the ST windshield, but it was with my bikes. The Scorpion was quieter than the Nolan with and without ear plugs, but I never felt any cooling air in that helmet unless the face shield was up letting air in, not a great summer helmet. Also the 700
FAILED the cold weather dot test one year so it's not necessarily a great winter helmet either. I won't be a repeat buyer or spend those many extra dollars on the heavy 1000. I'd sooner spend that extra money on lighter weight for all day riding at my age.
The Scorpion 1000 is a good deal heavier than the 700 (which isn't a light helmet either) and so the 1000 is completely off my radar.
The flip ups are heavy, they are noisy, and some level of less safe in a crash (but worlds better than a 3/4 helmet). They rock at gas stops and asking a fellow rider a question at a stop sign. I'll be back to full face when the Nolan has lived it's useful life, or some extra $ find their way to me.
The full faces are a few minutes extra hassle at certain types of stops, but otherwise outperform their flip up brothers for all day riding comfort and safety in my opinion.
