I've got a few POG mids and OS and 2 Borons - one bumperless and one with a bumper. Got a couple of grommetless POGs for fun and their hoops were definitely deformed but still playable.
I play the bumper POGs and Boron and they are superb racquets. Great power for me, nice spin and very mobile despite the substantial weight. And they don't hurt my wrist one but unlike my Pure Drive GT and Prince Ripstick. Old bumper POGs are definitely playable racquets.
That said I got a set of Donnay X-Platinum 94s and they are very POG like with the exception of being 18 x 20 and even more arm friendly.
