Throttle my friend, its all about throttle in the mud and not looking down at those bloody ruts!!! I try and find "alternative" lines in the mud, stuff like maybe extreme inside or extreme outside, where the mud ruts arn't so crazy. Few things to remember about mud; maintain speed, don't even think about using the brakes and body position plays a much bigger role. I ride a lil 125, so mud is pretty much the worst thing for me, so I personally try to stay away, but on a 4 stroke, you've got the powah and grip to get through those muddy situations no problem. Approach them quick, with a good amount of speed and blast through them standing up for better balance, trying to keep the front end light.
In my view/opinion, the difference between a whip and a scrub is how you leave the jump face. A whip can be done many ways, the most common is to do what you did which is twist the bars the moment you take off. Sadly, to perform a proper whip, you need a longer jump then what you had available for you at that track. A scrub is done by leaning the bike off the jump face, its kinda that simple. You don't twist the bars like throwing a whip, you literally just lean and the back will come out on you, just make sure you understand the consequences of being too stiff in the air when throwing a scrub, it can get dangerous if you freak out and land wrong. I'm way too stiff in the air and have had some close call's pulling stunts like that, even though its fun and I enjoy practicing it!
