Maybe this is too late, but having owned both, I'd have to say hands down get the '05. In fact, my '05 was the first frame that never broke on me. I had it for 5 seasons, then lent it to a buddy for a couple of months while his frame was getting warrantied, and then sold it to another buddy to replace his '03 enduro. It's a solid frame. Previous to that I went through an '01 and two '03 frames.
