My advice is also to continue with the sidecar.
With all due respect to QueenBee, riding a hack is something you LOVE. It would be such a loss if you weren't there to teach more people who are standing wide-eyed outside DMC what to do, or no longer posting mini ride reports on your Wumpa thread. I loved your adventures and enthusiasm, and would hate to see it go.
As to what rig to use, I'll let those who know better voice their opinions there. I have both an 1150 and 1200 (the former of which is my own DMC tug) and love LOVE them both for much the same reasons (they're AWESOME).
But my vote is to try to either recreate Wumpa or start a whole new adventure with a brand new rig.
And if you need to get rid of some of those farkles, PM me! ;)
