You really can't go wrong with either driver at that track. but from what I know of my boy, he dominates mid length tracks, Cali, Michigan, Texas, etc. Look at the schedule and find tracks in the 1.5 to 2 mile range, those are Biffles specialty, if there are alot of those type tracks after week 12 and not so many before week 12, pick Biffle this week, if there are alot of those tracks before week 12 and not so many after, pick Gordon..
Also, when Brostol get here, Gordon does well there also, but alot of experts are saying Biffle will be strong there this year.
