Honestly, I've always liked Rouen, and those versions (Short/Long/Extralon) are also well done.
But, and this is a big but, you always have to be very careful not leaving the track or you'll end up in the woods without any chance to get back on track. And this kills the fun a lot. Really dangerous parts are the downhill section, the hairpin at the end of the downhill section and the subsequent uphill section.
We had a race at this track two weeks ago, a bunch of ppl had crashed and ended up beside the track. There only chance to continue the race was resetting the car to the pits.
If this problem will be removed, those tracks are really worth five stars. :)
