I'll add to this. On rick and morty the wireform is a bad design not only from a ball drop reliability standpoint, but the fact that it's not very serviceable with rods bent over the bottom of the playfield. If you ever had to strip the playfield to shop it, you're pretty much forced to buy Terry's wireform because it has threaded ends that can be removed over and over (which I already have). Metal only bends so many times before it snaps.
