Well . . .depends. If your track adheres closely to ROAR guidelines the 3700's are not legal yet. So in this case the 3300's are the obvious choice. If they are less stringent like my track, the 3700's are the way to go. If you think about a discharge curve of 3700 vs 3300 the 3700 curve is a little longer. This allows you to get your race out of a higher overall average voltage of the 3700 discharge curve than the 3300 curve. Maybe someone else has a better explanation. I am sure you can find more info by searching.

This is absolutely correct. This is also why you always want to get the highest voltage, highest run time batts you can afford. A 415 sec pack of 3300's will have more voltage available to your motor at the 1 minute to go tone than a 390 sec pack of 3300's.
