I agree with Marks posts...the x6 is wonderful. The 22 is still in its early days so getting strong feedback at the moment is difficult. Most top lads who are running 2wd are using mid motor configs these days...although you can still see the old motor on arse models doing well.
Vega is raved about for build quality at the moment but as previously mentioned, the x6 is great and extremely forgiving on those mistakes we all make...there is also loads of set-up advice and general tips available for x6 on the xfactory section of oople. You can get feedback and comments on problems from the lads at xfactory directly which is brilliant in terms of support with your car.
Since the x6 squared came about (the latest model) the car is strong and easy to build....check them out here
