Oh that's good to know! I am looking for the lowest weight on my wrists with the most natural wrist angle as the priority. Everything else come second! I sat on an FZ-1 back in '04 and it felt really fine, and quite upright IIRC, but I have never ridden one. Outside of your legs, why did you find the FZ-1 uncomfortable?
It sounds like you are quite a bit bigger than me than me, as I am 5' 8.5" with a 31.5" inseam, and I have never ridden any bike that has bothered my legs, knees etc no matter how much of paperclip ergo it had.
The thing that just freaking kills me with pain after a few hours is any kind of weight, or stress, or unnatural angle on my wrists. I am probably a candidate for carpal tunnel syndrome.
On my VFR, after about 1 hour or 2, it felt like my wrists had red hot spikes punched through them, and it would take a few days to completely go away. If I kept riding, then after a few more hours, the pain would be so intense that I could not move my hands freely, and it would take more than a week to recover completely.
The next thing that always got me on the VFR was the skinny, forward slanted, hard ball cruncher Honda amusingly calls a seat.
I have had number of bikes before the VFR and never experienced the awe and shock of crushed balls, crucified wrists, and sore inner thighs. I felt like a cross between a rodeo rider, Jesus Christ, and a sexually abused cuckold. (Great image!)
