Zorkler,
I have had 3 wings, a 1988, 1500; 1996 1500 & a 2003 1800. They are great bikes and more comfortable than the FJR, one up or two up. As for windprotection they are better than a FJR. When it comes to handling, a Wing is very good. I used to take clover leaf off ramps at 50 MPH not probelm with little effort on my 1800!! They are quick too with a 0-60 MPH speed of 4 seconds compared to the FJR which is 3 seconds.
So why did I sell my 2003 1800 to buy a 2008 FJR, well it comes down to what I was using the Wing for vs what is is designed to do. I was doing commuting and only taking day trip rides, around 400 miles total, and my big trip each year is to Lake George, 250 miles from where I live one way. Doing most if not all of this solo, so I really did need a bike with this much capacity. One of the worst things about a Wing is slow speed traffic situations. ALOT of bike to be in that stop and go situation solo and even worst with a passenger.
I think a great comprise would be to have the FJR for commuting/short distance touring and the Wing for long distance touring. I remember going to Lake George with the Wing saying to myself, it is a great bike to get there and get back but wished I had a smaller, lighter bike for when I was up there and doing local rides on the twisties.
So what I think is, that the FJR is a great compromise bike. I have a Givi V46 trunk with backrest and will be getting a larger shield and possibly highway pegs. I did take the bike to Lake George this year for a week and it was great going up and great to have a lighter and more nimble bike to ride when I got up there. I could take off the bags or trunk or any combination while I'm up there too which is NOT possible of the Wing. You are always carrying around that stuff even if they are empty!!
I hope tis helps with your decision
