I have the Goldwing tall with vent. I am 5'11" with 32" inseam and 34/35 sleeve. My seat is a Mustang Tripper which seats the rider 1" lower and back. I am pleased. No buffeting nor drama at highway speed and the vent adds adjustability for different temperatures and speed.

I did did try the bike without a shield and that was a joke. Couldn't ride much faster than 40 mph without gusts ​and wind noise.

I also have a 4.5mm Polycarbonate VStream Windscreen N20012A (with vent opening) that will fit the 2001-14 GL1800 that came on the bike when I bought it. That windscreen is ~22" tall and 26" wide. Gave ultimate protection but I did not like the look. Original Price was $229 and willing to sell for $100 plus shipping or pickup in SW FL.
