I think number two has a swear word or two in that bright eyes song, but it's very minimal. Like those dudes said, two and four are the best. My all time favorite is two becuase for me, everything came together--extremely memorable riding paired up with great music.
Four is amazing with the most progressive riding in any video to date. but for me personally, I wasn't too into the music (obviously, everyone's taste in music is different so you may love it). However, what's actually in the video is well worth the purchase if you're into wakeskating.
I actually like issue number one as well, but it's quite different from every other issue. It does not have the same special effects and the footage is not quite as crisp either. It also used some lesser known tunes, which still seemed to work out well for the video. I really liked the aaron reed footage and the bi-level interview...and drew's opening section was nominated for "part of the year" from WBM in 2005. And this video also has mellow language, so you should be OK in that department.
Honestly, if you can, pick up all three of them at one point or another. You won't regret it.
