I've owned two FJRs, and two R3Ts. I really like the idea of the FJR, and I agree with all of your points. I am back on an R3T, and I don't think I'll trade it away again. It is a very comfortable bike, and it suits me. The FJRs are both gone.
I've also had other sport and sport touring type bikes. My favorite is the BMW K1300S.
When I get back from rides on the R3T, I am generally fairly relaxed, comfortable, happy, and thinking about my next ride. When I would return from rides on the FJR, I would often feel like I'd been beaten about the head and ears, and my shoulders and knees would be uncomfortable.
I highly recommend that you follow your inclination to move back to a Rocket.
