Personally - These machines should be treated with a bit of respect and belting them around achieves absolutely nothing as you are playing them for free anyway.

Wrong Nino, I have watched a good pinball player for eg, Dan the man where a clever nudge or push at the right time can save a drain or even prepare for a clever shot at a ramp or target.
People that dont like there pins being shook remind me of guys that buy 4 wheel drives and never let them enter a bush track or ever go off road because there scared it may damage them.
