Thanks all, maybe it's time for an update. I really appreciate the answers I got here, they made things a lot clearer to me (after getting me all worked up in indecision hell).
In the end, what I read is that people like both as far as performance/fun is concerned.
The argument against the Ducati, besides price, is that you have to keep taking care of the bike, which has many problems. On the other hand, I also see that the FJ is a bike you buy with the understanding you will somewhat
have to change it - everybody says the suspension will need changing; the "Abrupt" throttle mode requires me to ship the ECU to somebody to flash a fix - no thanks; cruise control (which I need) is a $800 semi-ugly add-on from mccruise; the seat seems 50/50 as far as comfort goes; what else?. Once I take care of all this, I still don't have the adjustability of riding modes/etc the Ducati gives me, the extra torque, etc. So the more I think about it, the more the Ducati makes sense, even price-wise - it is a much more complete package that comes ready to go. Poke someone (ok, Hooli

) who says he would probably have bought an FJ were it available, and he will tell you how much he likes the MST.
The only remaining real problem with the Ducati, from all I read, seems to be the expanding tank. When/if that happens, I'll get a Caswell'ed replacement, and it's done. Ah, and a screen protector for the self-scratching touch screen. Buying one when it was launched was a gamble, but it is a known quantity now.
There is no wrong bike here. Both seem great. But for me, the Ducati it is.
Thanks all! Now to make it happen...
