I have the '09 GSA model. Stock windscreen. Just had Bill Mayer make me a set of seats. Love them to death. I'm 5'6" with a 30" inseam. My wife is 5'4". We both love riding together on the GSA. I consider it far superior to the RT and, for that matter, even the Goldwing.
I find the wind protection is great. I ride it year round. Great touring bike.
'09 BMW 1200GS Adventure, '09 Vstar 950
'09 Honda Rebel, '77 CB750A, new garage (in planning)
Need more room for more bikes.
