Unless you are extremely vertically challenged you wont have a problem with obscured vision. I am 5' 10" and a very important half !! and I just drop the top screen down a little so the top falls below my eyeline.
the real beauty of this screen is that its just so easy to adjust , even on the move and the buffeting is almost non existant compared to the original.
perhaps someone else with a little more experience can confirm whether or not it will fit a gsa - aren't the screens transferrable between the two models as I have often heard that people fit an adventure screen to their gs so the reverse should be possible I'd have thought
