Had the Madstad brackets with a slipscreen (dark) which eliminated all the buffetting but a dark screen driving around London was a mistake. My aim was to reduce the noise and get a clear screen so opted for the Givi.
So far no buffetting (so a match to above), vision in town perfect compared to a dark screen it would be.
Noise slightly improved at the moment but only tried on the lower settings so still room for improvement although the Shoei Quest is not the quietest of helmets even on my old Bandit the Shoei from day one was 100% comfortable but alot more noise came through compared to My old HJC.
All in I prefer the Givi.
Anyway Givi staying so the Madstad and screens are up for sale if anyone interested its already posted.
