Hmmm, the XRR isn't as difficult to get the hang of, but it is VERY difficult to drive fast.
The FZR though is kinda twitchy at first and i found was a little hard to get used to, but once you do it's pretty easy to smash some lap times.
The FXR is just a joke, i'm not a big fan of people driving it, unless the whole race is a one-make.
