well, my younger brother and i own a ps3, and we have a Dualshock 3 Wireless controller. This is our main controller for single player use. What i was wondering, is how hard is too hard to flick the analog stick? We have skate 2, and you have to do a lot of work with the analog stick by flicking it up and down. But my brother gets into the game and flicks it REALLY hard.

Example: If you were to snap your fingers this hard, it would hurt.
Overtime, does this do any INTERNAL damage to the controller? Or does it only dent the plastic stick? (it shouldnt dent, but you know what i mean.) I just dont want him to damage it, and i want it to last a very long time. It's a $50+ controller. And knowing him, he wont pay for it if it does get less sensitive or break. Just some insight from some ps3 owners would be great!

There is a thin layer of plastic that connects the top of the analogue stick to the bottom and this will wear away and it will be harder to move is and eventually start tearing the hard plactic and break the stick.
