RE: EVO INFO
I have an Evo 70-04 that was one of the first produced and it doesn't have heel bumpers on it. It is easy to tell if the board has them by pushing hard with your thumb on the pad; start at the edge of the pad and you'll notice a discernible change if there is a bumper.
I also have an Evo 70-05 and the difference in rough bump/jump condtions between it and the 04 model is noticable. Not much difference in wave sailing unless you land you jumps flat.
