Tron L.E.-- I have played about 10 games on and dig the ramps light effects, and the flow.
AC/DC BiBLE --I have played and totally dig it! I like the added features and drop targets.
AC/DC Pro --I have played over 20+ games on it and its just straight up FAST with stand-up targets!

So I will have to say AC/DC wins but not by far. I always dug AC/DC as a teen in the 80's (Heavy Metal music period)! All you who say "unfair drains,etc." You need to get better at your playing skills. If it wasn't an ASS kicker, then some of you panzies (j/k) would be saying it too fricken easy!
