Ah, was wondering how you missed the second lot, must have been typing while the second post with the assembled mini-playfield was being uploaded.

Please use WHITE Rubbers ! It will look much better and match the already colorful and vibrant playfield. BLACK rubbers will look dull.

We debated that last night. The decision (just for the photo shoot - not locked in) was to go black simply because it is a modern game (2008-9 build) and therefore keep in the theme of the current industry standards. Also, we think the game is going to be crazy fast (ie like AFM) and the extra bounce might be too much. But testing will sort that bit. Personally I never use black on anything (except BBB which looks right black), so there's a chance things might whiten up before completion...

Thanks for the kind comments guys!
