I've recently been becoming a fan of these, so what's your favorite?
To be clear, a loopable shot is a single shot which returns the ball to the same flipper the shot was made from. Comboing two ramps doesn't count. For instance, the upper loop on The Getaway, the main ramp on Police Force, or the left ramp on Star Trek
I've been finding the upper side-ramp shot on my Black Rose can be very satisfying to hit over and over, even more than the whirlpool ramp (Trudeau seems to have a thing for loopable shots...)
