the 2 ways i like to do them now is
1. underwhips......... witch is a upside-down peg wheelie TO upside down tailwhip to dumptruck
or
2. x footed forward peg wheelie switch unto a dumptruck
there are just a few more that i can think of , such as a stubbleduck, or even going around the bike, and back again from the oppisite direction, but these 2 are the most familiar version you see riders doing today( more likely the 2nd version than the 1st)
