Hey guys. I'm sitting here trying to learn Closer to the Sun by Slightly Stoopid and I cannot figure out this one little riff they use for the life of me.

Tab Im Using:

Song: http://www.youtube.com/watch?v=SFGmnJQ_BF0

If anyone has any advice on how to play the "Part 3" riff it would be much appreciated. I sware that the way I'm attempting to play it just isn't correct and I need to figure out a new way to do it.
The way I was trying to do it was pulling of from my pinky to middle finger for those 3p1 and 3p0 or 5p3 and 5p2 pulloffs...if that gives you an idea of what I was trying to do.

Thanks for any help, and I hope this is the right forum.
