I have this model XR1100
http://www.bikers13.hu/images/termekek/shoei-xr1100-conquista-tc5.jpgit is very comfy. i used it on a 1200 mile trek around Ireland in May and had no problems.
I have a FZS 1000 gen1 with standard screen and find very little buffeting even though i am fairly tall at 6'3. some wind noise but then i doubt it will ever be fully eliminated. i generally wear ear pugs unless its a quick ride somewhere. Even at (ahem) high speeds i cant fault it.
with pinlocks in it never mists up even when i was out in February and it was -1c out on the road the day after it snowed round this way.
I have the chin skirt fitted and purchased the nose cone. not sure it is really needed with the pin locks but i like them and was only £10.
Without doubt the best lid i have ever had.. my only complaint is i find the visor lifts slightly when i look behind me at national speed limit speeds.
this causes a little whistle but as soon as you put your head back facing forwards the whistle goes. local shoei dealer said it could be adjusted to stop it doing that but i haven't had the chance to take a look.
they are expensive i know but i don't regret it.
