oep - Based on advice received in this forum, I replaced the stock 14" HD w/s on my 06 RG with a Clearview in June this year. Worked with John at Clearview who recommended a medium +1 for me ( as I am 5'11" and have a stock seat). Based on a recommendation from a forum participant here, I also ordered the center vent. This combination works well. In fact, the faster you go, the better the w/s works in terms of quiet air in the rider cockpit area.

Due to the fact that each rider's characteristics and expectations are different, suggest you call each of the companies mentioned above, ask your hard questions, and see what sounds best to you.
