Keeping sponsors longer
Once you win a competition in the Rank B contests in snowboarder mode, a person will approach and say that they want to sponsor you. Accept, and quickly save the game. If you lose the sponsor, immediately quit, and reload from the last save. You will have the same sponsor you had before they dropped you.

Gaining more sponsors
Girst get a sponsor. As you win more contests, more sponsors will hook you up. If you decline an offer, the person with the offer will ask if you will repeat what you said. If you accept it, they will be happy -- if not, they will look at you and say "we thought it was a good offer".

Winning more contests
This trick works in the Triple Air event (Rank B). Do Misty Twists, and as you start to flatten out (look more vertical), start spinning into 1440s, 1620s 1260s and so forth. After the three air jumps, you should be in a position to at least score more than the high placer.
