Quoted from Frax:

And for the record, the only time I WOULDN'T use a slide save in a tournament if I felt it was absolutely necessary is if I'm playing Demo Man by the handles. THAT *is* asking for cabinet damage.....and probably a shoulder injury, LOL. I dunno. I'm used to playing at home where my games are head to head, and the location I typically play at the games are head to head, so it's not really like I can do what's in that video above where it moves two feet..

I've never done a death save OR bangback, but I do slide saves all the time and no game I've ever owned and sold in 6 years has ever had any of these problems.....nor out of the ~55 games I've owned, have I ever purchased a game with any of these problems other than 'bent legs' (Frankly they usually look like such a pile of crap I don't care if they're bent! They're getting replaced anyways, so a little twist on them is kind of irrelevant!) that looked like it was due to abuse as much as NORMAL wear and tear, or overtightened leg bolts.
I'll give you the floor damage. The flooring under my pins looks like dog crap.

Quoted from markmon:

No. Machines were built to nudge and its part of the game. Any owner that says you can't nudge I guess I'd have to be done playing and want to leave because that person was too ridiculous to hang with.

Quoted from GregCon:

Um....those who fail to learn from Devo are doomed to repeat the mistakes of the past. Santana said that years ago, and it holds true today. Not to mention those who fail to learn from the very words of Pinball Wizard wherein (and I quoteth) "He stands like a statue/becomes part of the machine/Felling all the bumpers/ALWAYS PLAYING CLEAN". Now, if that isn't proof positive I don't know what is.
So, as we have all seen in pretty much any Ninja movie (and 'Ninja' is capitalized, thank you), there is always the brash youngster who shows up full of piss and vinegar who gets his ass kicked by the aged, feeble-looking bald Ninja master and must learn to rethink his ways before becoming a true Ninja warrior.
A true Ninja (or Tommy) would never need to manhandle the machine because he would always be in complete command of the ball.
Shoving the machine around is like putting Vaseline on the baseball or deflating the football a tad. It's dirty pool, old man. You might get away with it, but .....
Show me two players with equal scores and the one who didn't need to jostle the machine is the better player.
And as for the old 'pinball machines are meant to be shoved around argument' ... that's ludicrous. It's more like 'Pinball makers know that the machines will be abused by mooks in public settings so they account for that in their design'. Those are two different things.

Quoted from dasvis:

Get a life.
Nudging IS pinball & exactly how pinball started. The early pins had NO flippers. The only way to control anything was to nudge.

Quoted from flynnibus:

*snort*
It's as if you've kept your eyes closed.. Why do you think there are posts with rubber with these inlane gates?? To protect the ball or something?

Quoted from ramegoom:

I slide, jiggle and shove in a big way. In fact, I have slipped small plastic bags over every tilt bobber in my pins to completely prevent tilts and had installed nylon glides on all of the feet.
Been severely nudging and jiggling since the 60's when we used to hang at the pool hall game room and would place those bakelite ash trays under the front two legs to "level" the playing field. You could play all night with a single coin.
