Oh, I wouldn't be so concerned with tricks as much as I would consistancy. Be dialed and whatever you do will look good. Better to do a perfect run of easier tricks than a sketchy run of hard tricks.
You need to write down your tricks and combos. You need to do them perfectly 5 to 10 times a day. You need to put the combos in an order which varies your riding from front to back wheel, spinning to rolling, forward to backwards. Do not be repetitive. Do not be repetitive.
