Just called the hobby shop to get a second opinion. He pretty much agreed with me, the "c" rating is for the "punch" off the line. When your using a 2250Kv truggy motor in a buggy your really not too concerned about the "punch" because your going to smoke the tires no matter what "c" rating you use. Does everyone else agree with this? If so I am going to order those 20c rated batteries.
