driving the indy is brilliant .. until..
you reach the higher speeds (90+) as the wind
or poor helmet design creates such a vibration
that everything goes bluury.
now i tried firstly with no helmet just ski goggles.
it wasnt too bad.(until a fly hit me in the forehead)
then wearing an AGV stealth.. it was the awful made you feel ill.
so onto a nitro n500v it was ok better than my first 2 attempts.
im going to try a helmet with i chin spoiler today. ill report back
Just spend money on good quality.
AGV etc ive found are ok for low speeds, but i found that when you hit 90+ (163) mph (on a track of course!! 
) the vibration makes riding more
dangerous.
The only lid ive ever had that avoids this, is an Arai Condor. It cost me £400 when i first bought it, but well worth the money. Comfortable, light,
small and doesnt vibrate.
If you are using the standard MK flat short screen I found the buffeting by the vortices around the side edge at those speeds to be a nightmare in a lid. A change to an aeroscreen made a massive difference for me (Arai Corsair lid). No lifting and very even wind.
ive got an aeroscreen from the chap on ebay.
without a helmet the wind hits me in the forehead but i cant set the screen any higher.
just been to hein-gericke and bought a HJC IS-16 its pretty cool looking thing has built in shades 
it only starts to vibrate and wobble about when you get +100 (or so ive ben told 
)
i may well buy something better but after my recent problems funds are a little low.
thank you for all your input i will refer back to this when i next buy a new helmet
if you were short and had an aero screen is driving with no lid going to be o.k? or would you just get hammerd by the wind?

) ive done 100 or so miles in the indy this afternoon
this new helmet is alot better than the AGV i was using before
altho its not helped my driving ability
I don't use a helmet for safety but to avoid the wind and bits hitting my face.
For that reason I use my skydiving full face helmet.
They are expensive but they have excellent vision and designed for going faster than 120mph.
