Quoted from frolic:i think we are noticing the dimpling more because the playfield is so well lit.
It's also the TYPE of game. High energy high speed games get 'em more than others. For example I have my MM next to CFTBL... MM is shiny but evenly dimpled... high speed and troll heads throwing the ball around do this.
But CFTBL - older and more played... has virtually NO dimples... slower game and the ball never leaves the PF.
Just politely rolls around
You're right also - LED's definitely make those dimples glitter.
