I don't play BTB so I would say Reflection or Uncaged. Reflection, red side gets rockets, shotgun, and if you play like me sword right off the bat. The only weapon blue gets is sniper and that's only if you don't have a jet packer on your team.
Uncaged same thing, you get snipe, GL and if you use the rocket jump you get rockets, the only weapon blue is certain to get is the shotgun which is pointless on the mp anyways.
