It seems like a bunch of people are having trouble making the left ramp from the crossbow. On my game, even a perfect shot will only make it part way up the ramp. I can, however, make it up the right ramp with consistency. I started this thread to find out how widespread this problem is, and to see if we can figure out how to fix the problem.
The only thing I can think of that might be causing weak shots on my game is the way in which the ball lays against the plunger. The plunger is making contact with the ball well above center (see photos). This may be inhibiting the full transfer of power. If this is indeed the cause of the problem, I'm not sure the best way to go about fixing it. Perhaps there is some way to raise the height of the ball without adversely affecting anything else.
