I like the smaller packs also. But most club races will have at least a 15 min A main, and any race with a good turnout will do 20-30 minutes.

I can change out the packs, like I did at a race last summer, but with the 8000 pack I don't have to worry about it.

I really would like to try a 4900 Flightpower or Kokam pack though. That would be light and super fast.. and still good for a 15 min race, and if my results from last weekend are accurate it may just be enough to do a 20min main.

Hmmm....
