Quoted from FlopTube:A couple pieces will make a difference and will be nearly invisible. If you have some laying around it would definitely be worth a try.
So you just put the mylar on the edge of the metal a couple pieces, or you wrap it all the war around the edge too? Just the tip would be enough to make a difference?
The worst is during multiball start now, as I got the left orbit adjusted as far as it will go yet the balls still roll down and hit the bottom of the sling which will sometimes launch em, or they just bounce off the bottom tip of the sling and go straight to drain down the middle. During MB start, the balls are ejected slowly and the slow roll makes them just want to bounce and go to drain instead of a flipper which is getting frustrating.
