I was all set to do exactly what you're doing, switching a SG batwing over to a shark. However the test ride on a RG dissuaded me totally from doing it because of the wind buffeting. I am 6 ft. I love the more leaned forward seating position and the handling of the Roadie but just couldn't get over the wind knockin me back and forth. Maybe lowers on the RG would help, but to me the best combo is a batwing with lowers.
