I was in the same situation I bought the juice w/attitude for a couple reasons there seem to be alot more people running them so if I had questions about it someone here would probably know. and no one would tell me if the evolution display was the same as attitude in size and the way it is made, because i really liked the looks of the overhead mount PMTdiesel makes for the attitude that fits in the little sunglass covey hole. Also no dealers that I have been to that sell aftermarket stuff had the evolution to look at. I like the attitude but I dont think the display is super accurate.
