I would follow Tom's advise if you are having trouble deciding what you want to do. I have done both. Running local dirt is pretty tough competition and you will spend just as much money trying to run up front as you would running with HOSS or AVSS. A pavement car is not that much more expensive than a dirt car, I know I have had both, and in fact costs about the same to run HOSS or AVSS as it does to run local dirt you just have to manage your tires well on the pavement deal. The only reason we went back to running local dirt was that HOSS runs most of their shows in northern Indiana and AVSS runs mostly in Michigan and the travel costs made more sense to run local dirt. If you have never heard of HOSS or AVSS here are the links to their web sites. Check them out.
