Having found a ZTechnik VStream available nearby, I snapped it up, as I didn't find the stock screen on my 2010 RT as effective as I would like and second hand VStream screens seem to be very rare. I think it measures about 27" from top to bottom, which I believe makes it the tall version.
However, at only 5'10, I think it's just a bit too tall for me, cutting off too much airflow to my helmet at the lowest setting, even after raising the seat height.
So, is there anyone in the UK with the standard height VStream screen who would like to swap it for a tall one? I'm based in Nottingham, but happy to travel (within reason) to meet up and make the swap.
Thought I may as well ask!
