It depends on what you are doing and what problems you are trying to deal with.
For most beginners excessive yawing is a problem. You're paddling for a wave but your power strokes are getting you sideways.
You can fix the problem by: - starting side on to the wave and timing your strokes so that when you reach full power you are going in the right direction. - getting good at paddling and swapping sides. - put in a ferking big centre fin. I have a 10" Jimmy Lewis that works well.
