with the stock screen on both my Ultra Classic and CVO Ultra i do not suffer this buffeting you talk of, may be a slightly higher screen would solve the issue for you on the UGLtd, i am 5'5" and can ride 80+ without hiccup, but then i am also used to riding with out screen and with apes
15' Windshield and no more double vision. only issue is you have to look through the windshiels. Little hotter but i can open the vents and the air hits me in the chest, not the head.
