louis- thats a micro track! lol. no one really runs 6 cell 12th scales anymore since it really kills the tires (the car is so heavy) and you mind as well run mod to get more speed, or 19t (which all of tracks do now).
i would highly suggest the speedmerchant (either 6 or 4 cell version) since it does the best what you are looking for (quick transitions). also with the new front end coming out it will have plenty of steering to get around that track (right now the old style front end is great, but the v-force should be alot more adjustable to tune to each track, which in your case will help you out alot, since its far from your standard carpet track)
