Thanks everyone for their input. I know these sorts of questions get asked on here all the time but it's good to hear peoples opinions.
Personally I want the Schumacher because it's similar to my KF2 of which I have loads of spares for. I am worried that the car is going to be difficult like my K1 Aero. The K1 can be fast but very edgy at times. Generally I'm almost as quick with my KF2 so really not feeling the advantages of 4wd.
I know the sensible choice would be to go for the xray as they run very well at both the clubs I race at.....
I think I should just wait and see how the cars are all doing.
