WoW Dragon riding: Extra speed trick!

This video demonstrates the "Skyward Ascent Dolphin" technique for squeezing additional speed out of each charge of Vigor.
To achieve this effect, you need to be already travelling at full coasting speed. In quick succession, steer sharply upward, hit Skyward Ascent, and then drag the mouse back down to redirect the boost from SA horizontally.
It takes a little practice to get a feel for the rhythm, but as you can see from the speed plugin I'm using, you can attain speeds as great or greater than Whirling Surge, and the boost lasts longer than Surge Forward.
Happy flying!
