So many great ramps... For me its there two things to this.
1: Making a tough ramp shot
2: The flow of the ramp.
The jackpot shot on Mousing around is ultra tough so making that is very satisfiying, along with the right ramp on TOM.
Nailing say the middle ramp on TAF is also great because it relatively easy and the flow is nice.
The left ramp on STTNG is a great shot since there are two outcomes.... The borg ship and warp drive combo (the best combo in pinball imo)
Then you have the shadow, getting vengeance and continuing to get super vengeance is great.
I like the look of wireform but I like the feel/smoothness of plastic and metal plated ramps.
As for the best flowing ramps you cant go past MB. That left ramp is just beautiful.
And then you have Demo man... Ahhh theres just too much to chose from...
