Juggernaut - Welcome to the board.
You answered all your own questions in your statements.
You want the 12 and the 12 is the right bike, especially for your size.
Here's is my brief review ....
We worked out a demo ride on this bike, and I went there really wanting to like it. So, a few weeks back I rode a 2003 Gixxer 1000.
I really loved the look it has. But that was about all it can do for me.
I found it to be uncomfortable compared to my 12.
No where near my 178 r.w.h.p.
I felt cramped and I'm only 5'8" @ 220 lbs.
A skilled rider may have an advantage on the 1K in the really tight stuff,
but I would be very close on the PMB.
On a straight away...no contest. Remember we are talking real world here, not magazine article racing.
Roll ons... no contest, the 1K has no where near the low or mid range of the 12. ( Maybe with better gearing, it would be ok )
If you keep the 1K in the very upper rpms it's a runner..
If you keep the 12 in the upper rpms its a missle.
The 12 wins hands down in my book.
And that is my complete unbiased opinion
I really wanted to like the 1K, but it ain't no Zedex 12
