If I were making a perfect custom AC/DC for me. I think I would have parts of both games.
I would have the playfield of the pro. I like the Angus face much better than the look of the lower playfield and the gameplay of the lower playfield doesn't seem to add much.
The biggest thing I would want from the premium is the bell. I love the way it looks, I love the way it swings, I love the way it makes the shot less dangerous.
I would take the drop targets. I especially like the one on the left when firing the cannon.
I wouldn't want the ball cross over from the left ramp to the right. It's a bit of an eye sore, it displaces the right lightning bolt and what is really so hard about hitting the right ramp to load the cannon?
The train from the premium is nice, but I would honestly take the picture of the band on the pro over the chincy looking moving band in the premium.
I also like the different colored lighting of the premium.
I would also probably pull the display and put a standard DMD in it. I really liked the LED display at first. It looks brighter than a standard DMD. I even thought about trying to get one to put in my Black Spider-Man, but after looking at them more...I think they are a bit crap. The display is sectioned off into noticable squares and I have even seen them where 1 square isn't as bright as other and it is an obvious eye sore. I hate to pick on the Predator video, but it is the best video I could find to show off the look I don't like about the LED displays.
