I'm going to go with something that might be a less popular opinion atm:

2 run and gun 'bots (1 low goal, one high goal) to destroy the tower and outer works
1 fast, heavy, tall defender

I think low goalers of equal driver skill will seed higher than the high goal counterparts since they'll be able to input more balls and destroy more defenses than their high-goal counterparts (thus get those rank point more consistantly), even if the high-goal 'bots score a little more than the low-goalers. Thus they'll be your alliance captain.

High goalers score more points when undefended, so they will draw the defender away from the low-goal 'bot, giving them free driving room.

Defender to block shots and get in the way of opponent's best robot.

Everybody approaches, 1 or 2 climb (only if under 15 seconds).
