Riptide GP2

This will likely be earned during the Shoot the Loop Event in the 5th Cup, Waverider, as the target is 1500 points. While the same strategies can be used as in Stunt Master, you likely won't have the Tier 10 Tricks available when you first reach this Event.

I have recorded my run, using mostly Tier 5 Tricks. Note that you do get fewer points for repeats, but there are so many jumps on this Event that you should still clear the target.
