Yea one of my friends has the 2004 Premier and another one has the 2003 Premier. I liked the 2003 a little better but dont get me wrong the 2004 premier is a really great board. The main difference is that it is a centimeter bigger but try it out and tell me what you think.
I bought one a month ago and love it!! Take out the center fin, once you do you won't go back!! Here is a pic from yesterday, I used this pic because you get a good view of the board!
its alot wider in the tip and tail for exsplosiveness and is a little more aggressive with the longer outside fins. it does ride different than the 03 premier
if you rode the 140 of the old shape, and you are under like 180 lbs....ride the 136 of the new shape. The board is a lot bigger and slower....the people who have stepped doen in the size seem to like it.
