Funny - I've got a FZ8, which is a detuned FZ1, so you'd think maybe I'd find the difference between that and the MT too much. But in fact, although it is noticeably sharper, it suits me fine. Most of the time on the road I'm in standard (middle) mode - A is a bit too responsive if you hit traffic or a town, and B just feels flat.
What I did notice, when I took the FZ8 for its MoT the other day, is that the throttle on that is quite a bit heavier sprung. Maybe with the lighter throttle on the MT you're just grabbing a bigger handful than you think? Also on the MT there's zero free play in the throttle cable, so again it's easy to give it a bit too much until you've got used to that.
Mine's a 2015 model - ABS but no TC.
