2. The up/down you can notice in your hands on belt drive isn't only the motor, you have 4 big wheels, driveshafts etc still doing all that, you'll still have plenty of nose attitude throttle adjustment available over jumps
3. People on here make it sound like shaft drive is a disaster due to torque steer, remember the last 3 worlds at least have been won by shaft cars, and on the higher grip uk tracks before 2010 the last 3 national series winners at least were shaft drive, at least as far as I recall?
So I would have thought any problems would be pretty minimal to be honest!

The worlds being won by shaft cars is mostly due to the fact that there are more shaft cars being raced than belt, and it also very highly depends on who's driving what, which hasn't got much to do with whether it's belt or shaft. The last worlds are a perfect example...
The reason why shaft is so popular is the maintenance, and that's all there is to it. Come race on european tracks, and you'll realise how dusty most of them are and how very quickly an open belt drivetrain will get destroyed.
Torque steer I agree is barely noticeable on an off road car, that is mainly due to the high contact patch, the track width and the nature of the grip provided by the tyres, it's hugely noticeable on TC's due, again to the size of the contact patch, track width and type of grip (plus there's more traction with TC in most cases).
