" Going from a GW to a GW shouldn't take a lot of convincing if the plan was to simply go more sporty and the F6 option is there."

There is a BIG difference in the handling, quickness, and comfort between the GL 1800 and the F6B. Although on the same platform, lowering the center of gravity, weight, wind drag along with a more comfortable seat allowing for more legroom makes the two models totally different. I came off a string of ten Harleys before purchasing my first Gold Wing. Prior to that, I rode smaller Hondas, a Kawasaki, BMW, and even a Zundap. When I switched to Wings a few years ago, I was extremely pleased with the quality and reliability. The F6B simply suites my riding style these days. I no longer want to do the cross country jaunts of my past riding years but stay fairly local and ride every day. I have put 5200 miles on this new bike since Febgruary 26, it is just a pure pleasure to ride.

This, and two other forums devoted to the F6B are packed full of useful information from owners that really love this motorcycle. Good luck with your due diligence and making an informed decision.
