Well after 13 days riding in various conditions, rain for 4 hrs, windy & hot (Death Valley 36C) & some mornings in the -1C. I didn't test the Pin Loc internal screen on this trip although I could used it a few times.
First the Shoei Neotec was so much better than my HJC Symax 2 for noise (I do wear ear plugs) even though I usually had the SMH10R at full volume it seemed I could hear the music a lot better. And when I didn't have music I can say that it is a much quieter helmet.
As for ventilation, I found the Neotec so much better with the top vent open I could feel the cool air blowing over my head. But I will say that on my R1150GSA I have a tall shield & this did effect how the noise & ventilation performed, as when I stood up on the pegs the ventilation worked a lot better.
Noise was also more with the top vent open VS closed & having the face shield open to the first notch & behind my tall screen (I'm 6' 2" & my nose is at the top of the screen) I got some ventilation & it didn't seem to make as much noise vs having the top vent open.
The Neotec is very comfortable & I found that it sits a lot lower on my forehead than the HJC Symax 2 does.
The internal sun screen works great & I found that it did provide what I think was the same blocking of the sun as my dark shield I have on the Symax 2. It does take a while to find the slide button to operate it but I think with time you get to know where it is on the helmet.
As to the Sena SMH10R it worked great I had no issues with it linked to the SM10 which has the Montana rugged mount audio out hooked to the AUX of the SM10 & I have a small mp3 player hooked via 3.5mm to the stereo input of the SM10. This worked great when we were trying to find hotels in Las Vegas & getting directions from the Montana, the SM10 muted down the music so 'Karyn' could tell me were to go
I would recommend the Shoei Neotec to anyone looking for a new helmet.
