I tell people here locally to run something that a local sponsored fast guy runs, in our case there are 3-4 brands to pick from. Why, because they are supposed to help with setup, questions etc. A fairly good driver that doesn't have experience with setup will struggle, especially with todays new cars. If they have a local guy that knows the local tracks is a big help. Running the worlds winning setup may not help a Intermediate on a totally different track.
