I ran the X6 last year expecting it to be a bit of a handful but it was no harder to drive for me than when I'd run a B4 round there. You couldn't get on it as hard as a rear motor on corner exits (especially with any steering lock on) but that's no different to mid on astro in the rain.
There were two parts of the track where you had to be VERY disciplined and steady on the throttle, before the jumps in front of the rostrum and going downhill after the stepup in the middle. In both parts of the track so long as you made sure you were pointing where you wanted to go and accelerating in a straight line you were good, IMO mid is better on every other part of the track.
I'll be running a C4.2 this year, sugar or not
