Sorry I've been occupied as of late. Anyway I intend on continuing UndrWorld videos until they no longer seem useful. In other words, when we run out of crap to put into them.
Sokoto, if you check out
www.undrworld.8k.com you can sign up and ask anything you like in the Q&A section. No matter the question we'll do our best to answer it. So don't worry about asking something that is very complicated, or incredibly simple. We'll do our best to help. ^_^
FantomKitsune, it's still up in the air if there is proper application for some of these techniques. Wing Canceling can improve moving speed from platform to platform among other things. I was merely preforming tasks after Wing Canceling to show how easy and fast the technique is.
KokiriKing, there is no UndrWorld 1.1, however I've looked into this. Only three of the videos go on long enough to each the 2:30 mark. My guess after watching each is that you are referring to either UndrWorld 1 or UndrWorld 2. Both of which include a segment on Shield Dashing at 2:30. Shield Dashing isn't unique to Pit but is as I've stated more times then the people in the Pit forums wish to read how important I feel this is to competitive Brawl. Shield Dashing, and PowerShielding for that matter, allow you to cancel your dash animation and then any move wish to preform faster then you could if you were to merely stop yourself from running. In other words, putting on and taking off your Shield quickly cancels your Dash faster then any other method.
As for the skid, that's just Pit's normal Initial Dash animation. Think of it like a Fox Trot segmented by PowerShields.
