I learned to surf this season behind my new X2. First board was an 04' LF Skimskate. Had fun learning on it, but after much deliberation went with an Inland Surfer Black Pearl Yellow. I also just upgraded the ballast to the fly high.
I've been trying the 360 since getting the new board mid-August. Initially tried it with the stock small fin the board comes with. Had a lot of trouble with over-rotation. Tried my friend's older Blue Lake. I was able to break it free 30% of the time and liked how easy it stopped, but never hit one on that. After learning to ride on a skim style board, the long board just didn't work for me.
The BP Yellow came with a set of the white 6.5cm speedlines. I tried those on the outside and the board felt great for slashing and cruising. Had a hard time breaking free though.
Tried just one of the speedlines in the center, and got comfortable breaking her free. Finally hit my first 2 360's yesterday.
Now I'd like some comments on how to make it happen easier. This was the second ever 3 I've hit. http://www.youtube.com/watch?v=gII58zh8Kis
