Happy to say that I am officially a member of this club now )
Game is gorgeous. I added a different airball protector than Art's (odd, I actually looked in the marketplace and searched for all mods for GB and couldnt find it at the time last week) as well as the ecto goggles protector (the clear one that wraps around the whole thing) that I saw on Junky's GB premium.
Happy to say that I did not need to adjust the left side kick out (currently, it bounces off right flipper), also the scolari brothers drop down targets seem to work fine out of the box for me (any decent hit will drop them).
I did end up adjusting slimer today, 1: it seemed like only a perfect dead on on right in the middle smack would cause a registered hit, so I made it more sensitive (thanks for the advice Junky!) 2: while adjusting the switch, I wondered of raising the assembly up slightly would keep slimey from hitting the bracket on his way down, low and behold it did.
Very happy so far
