IMO you will just have to try the different bodies to see which one works where and for you. Not everyone sees the same diferrence in bodies, i.e. I may try a body and feel that it makes my car push, you might try the same body and feel that it makes your car loose. Also nitro cars suspensions are designed differently than electrics to compensate for the higher CG, specially the newer ones.
I also feel that sometimes the bodies dont have as big an influence on handling as some people make it seem. IF my car is setup with a stratus 2.1 and then I decide to try a Alfa Romeo, sure my car my not handle the same anymore, it might have a push for example. In that case all I need to do is put a softer spring on the front and that push will be gone, and the car will handle the same as it did with with the the Stratus. Of course,if the difference is too big, I might have problems in other areas. But I fell that generaly all the bodies are close in handling.
