Quoted from f3honda4me:They are a lot of work to put on or take off, and they affect gameplay. Sometimes they can be really bad on gameplay. I would tell you all day don’t use them in home use. The dimpling is way overblown IMO, it doesn’t affect gameplay and you don’t really notice it unless you’re really looking for it.
Dimpling on Sterns can be really really bad especially on new playfield. To the point valleys are created and inserts launch balls in the air.
