Couple things to add.
John Goerge is a fellow Tx AI racer. Good guy and I've have been very happy dealing w/ him.
Fast Track suported CMC at Nats at Miller. Did a ton of dismounts and remounts for CMC tech - for free.
Phil's also provided great trackside service at Mid Ohio.
I would pick those who have given back to the sport. Fellow racers are top picks as well Tommy and JG fit hat bill.
