When you take the middle cannon, there simply doesn’t seem to be enough power to go through the loop for the potential chance Hole in One, and puts you on the side, making the middle cannon pointless really.
How about a speed boost in front of the loop at the indicated spot to solve this? Or alternatively towards the end of the middle?
