I studied the Ghost Busters Pro flyer tonight & came up with a simple mod that I think I will definitely add to the
GHost Busters Pro game,

Instead of the fitted white flipper bats, I thought bright green flipper bats the same colour as the bright slimer monster toy and then add white super band rubbers on the green bats. This would look so much better IMO than the std boring white bats. White rubbers would need a clean periodically but bands are cheap n easy to change.
Even green bats with purple rubbers would work well. If u have a look at page 2 of the Pro flyer, on the bottom right the picture of the slimer monster is there. He is bright green with a purple tounge. So purple bands to match his tounge would match if set against bright green bats.

You could also play around with purple or yellow bats but the green ties in nicely with the slimer toy.

Also on the Pro, you could easily add some splashes of bright green powder coating to the black metalwork side rails and lockdown bar making it look like the slimer has left a trail on them. A simple and nice way to customise and dress up your Pro model & make the machine unique. Same for black legs. A splash of slimer green.
