If the track is pavement smooth the CW is a good car, if however you run on a real dirt track that changes every heat give the Klein a good look, but if you are looking for the best bang for the buck look at the bullet proof car it is darn near indistructable I have seen one put the nose of the car through a piece of 1/2 inch plywood and be thrown back out on the track and finish, neither of the other two will do that, one will break (CW) the other will fold up (Klein) Just my opinion but I think the BP is much easier to set up and handles more neutral. iIf you can talk Fischer into giving you his set up for the CW it is wicked fast, like wise with the Klein but Cris Cramer is the man when it comes to setting one up.
