Thanks for the info, Tim.
I'm a measly 5'6" and I do not even own a HS to begin with, but I'm planning to own one in a few weeks (or by february latest).
I was expecting an answer like yours: the sheer model of such a helmet will probably cause problems at higher speeds (with Hypermotards for sure) but I could not find any reviews with this particular helmet on the HS.
I wonder whether, considering my height and the Strada's tiny screen, I will experience the same problems as you had.
Have you tried sitting more backwards (or closer to the screen)?
