Quoted from thewool:So how many other people have lightning flippers installed? I asked the guy when I bought it if these were standard and he said yes, but it was also set to 5 balls. I set it back to 3 balls and the game has always felt really hard to me, which is great, but I don't want to make it artificially so....
I purchased a one owner from new WH20 last year and it came with all the original envelopes and goody bags. In one those bags was a spare set of plastics and a set of lightning flippers. So I'm guessing it came with both for the op to choose what he installed. The game kicks my ass enough as it is, never mind putting those on!!!
