in spots where it feels like you need to keep a flat base to keep speed stay as flat as you can - while still favoring one edge over the other. you can even kind of 'micro carve' and switch from flat/heel to flat/toes.. its when you get truly flat-based and standing up tall that you catch the worst edges.
that's another thing: keep you knees bent and stay aggressive. too many people get to the runout or the cat track and they stand up perfectly straight and start fucking with their iphone and the next thing you know - scorpion!
get the hell off my lawn.
