Share 'Breaking in New Plastic do you let the trees do the work'

I would like to know the different styles of breaking in new plastic. I have been told to bend the edge around the disc over and over. Been told to take it and beat it on a tree. Some just take them and let time do the work. do you speed up the break in time. One guy puts new discs on the seat of his car and sits on them....sorry but my discs would fly like shit LOL.
