As long as you're having fun you dont have to change. But just like the guys before I would recommend upgrading to some newer gear just because the gear has
progressed so fast the last couple years. I agree with Nate, the LF watson is really forgiving, a good freeride board for us who just ride 1-2 times a week.
For bindings its all preference, it depends how much ankle support you want.
For tantrums just follow this link or read my bs below: http://www.youtube.com/watch?v=WcgtM7Dxtxk
The tantrum is all about edging hard towards the wake. It sounds suicidal but here's a step by step process:
1) cut out on hard on your toe edge, begin a progressive cut into the wake
2) by the time you reach the wake you should have a pretty decent edge into the wake.
3) Stand tall on your board, with a some pressure on your toes (If you do the entry and take off correctly, it should feel similar to a tramp backflip)
4)As you stand tall, remember to straighten your legs and drop your back hand(right for reg, left for goofy), this squares your body to the wake.
5)As you leave the lip, start and keep looking back over your spine (act like someone is trying to pulling your hair from beIhind you and you cant break free).
It 's going to be awkward at first, but soon it will make sense. To speed up your rotation suck your knees to your chest and to slow your rotation straighten your legs oot like a gingerbread man.
good luck! I cant wait to see videos!!!
It really helps if you can remember the feeling off a trampoline. Dont forget to show us some vids!!!
