Quoted from 85vett:
If I could get my orbits to be as smooth as a pro then I would be a real happy camper as right now, that is the only plus to playing to pro for me.
85vett, I am getting consistently GREAT left orbits lately! Fast and smooth all the way through. Not sure how they compare to a Pro, but it is very satisfying to hit 3 left orbits in quick succession from the right flipper! Left, Left, Left - Yes!!
1> Removed the upper in-lane bumper rubbers and replaced with heatshrunk coil sleeves.
2> Enlarged the mounting holes in the diverter arm assy (below the playfield), permitting and ever-so-slightly forward positioning of the diverter arm. +1 step on my stepper drill bit.
3> I can confirm the left orbits I get now are much more consistent/faster than I previously got with the bracket mod, and right orbits are perfectly consistent!
I did have capgun's diverter bracket mod installed and was getting good left orbits, but did ultimately notice I was NOT hitting Mystery and Extra Ball shots consistently from the right. Seems the bracket was causing right orbit shots to bounce past the elevator entryway. I am certain I could have re-tweaked the position of the bracket to allow success on both left and right orbits, but I wanted to try another path first.
Again, the bracket mod seems fairly sensitive to left-right position relative to the diverter arm assy. I am confident additional tweaking would have gotten me to a similar end-point - but, was just a bit of a pain in the butt to adjust without removing the upper playfield - trivial with it off, but the upper playfield removal process is a bit of a pain all on its own.
I had thought to wait for Stern's fix (?), but this combination was reasonably simple to implement.
