I agree with everything except with the 50 SP for the additional hit, I think you can make more damage if you choose the 3 50% Atk boost with the +50% damage to SBB normal hit since it's still multiplying the raw atk... though obviously won't apply to the other units, but I have to test it to see which one is better.
