I like the dark effect while playing BSD. The darkness of the blue and red has a settling grip when the machine is turned on or off. Stacking is a must for me when playing pinball.
With I500, it is such a bright hangover with all the colors and shaking. It's fast, but I could do with out the flash.
Ps. If your going to redue the flippers on BSD, know that the left and the right are not the same coil strengths.
