For this achievement, load up a race on Ghost Creek. It has a series of close jumps including a vertigo jump. Below is the chain of tricks I used to unlock the achievement.

Off of the first jump before the big one do a modified + Down to perform a Lazy Boy then immediately release the modifier while still holding + Down into a Coffin. Once you hit the vertigo jump with a good pre load do a modified + Up to perform a Shaolin and release the modifier the same as before into a Bar Hop. Now you will have the next set of tricks available and you'll still be high in the air. Right away, do a modified + Left to perform a Running Man and then release the modifier again into a 9 O' Clock Nac. By the time you land you'll have the tricks ready for use. At the next jump pre load and do a modified
+ Up for a Scorpion Fender Kiss and release the modifier into a Ruler. Take the corner to the left as it allows for more hang time and then do one more trick and by the time you land you'll have your special trick and your achievement with but a couple seconds to spare. It might take a few tries to perfect so just keep trying.
