Alright, I'm gonna take a step back here and state two things about GnR. The good things.
1) Slash. He's awesome and was even involved in the dev process. I have no idea what that really means or how deep that is, but good on him. Axl Rose still the reason why I put headphones on when I listen to this deck. Last night was a King Megatrip remix featuring... AC/DC! If you like mashup mixes, check out: http://megatrip.blogspot.com/
2) Multiball ruleset. It's quite good. ramps to a small super at the left lock lane, ramps and the super jack at the upper loop. Way sweet! It's just that, that makes it great for a comparison to a system 11 game. The modes are lackluster, unbalancing and for the most part, uninspired. So I rock the multiball utilizing a backhand shot from the right flipper. Over and over and over and over and over and over until multiball activates.
I will admit that, putting up 2.34 bil last night in league was satisfying. Select super pops, hit the multiball... rinse and repeat!
As for the Wh2o comparison. Most of the shots from the lower left flipper are not in the "sweetspot" of the flipper other than the lane through the pops which is most dangerous.
