My problem always used to be that when I'd give it full throttle from standstill, that I would get jolted back to the rear of the seat which would unsettle me - however since the new seat, as long as I hold my body weight forwards (in a 'racing position') I have no problems with the front wheel popping up. It's only if I'm leaning back and slightly more upright where the front pops up a very small amount. (If I have a pillion on the back then it's nearly always coming up on hard acceleration though!)
The only time I tent to find it coming up more than a few inches or so, if when I mess up pulling away from a junction and I end up dropping the clutch
