In my mind, the Outer goal has the highest scoring potential, but it also assumes your opponents will let you get into scoring position.
Assume you are waiting in front of the ball chute to collect the bonus ball. What's stopping a heavy brute-bot from just planting themselves 1" behind you and keeping you there. It's not pinning because you can still move, just not very far
At least the 5 point goal is accessible in autonomous, and much harder to block.
Seems to me that you need a "get some points" safety play to go with the "hoard and dump" play. At Nationals we saw some great robots who filled up with pucks and then got blocked from scoring. Not so likely in early qualifying rounds, but very common in eliminations.
Also, there's nothing stopping an opponent from sitting in front of your ball chute and preventing you from getting the bonus ball. So, now High goal auto balls have the same point value as the outer goal.
All I can say is .... Scout, Scout, Scout...
