I traded my Katoom 1290SA many years ago due to this issue as well as my Duc MS Enduro last year, but may be leaning towards a GSA this go around. My personally important question is, how bad is the turbulence or buffeting for someone who's 6'2" (and shrinking) for the Adv version? I really hate playing the "try this windscreen, no this one is better," game. Any thoughts are greatly appreciated.!
