Steeper hills will be more ideal for hump'n'dumpin'. The speed and velocity help hold you on the edge of your board while carving.
At slower speeds, I would recommend a more finessed version of the same. The concept is similar, but without nearly the follow through. Calculated and cautionary shifts of your weight. Dropping your front shoulder in the direction of the turn may also help you feel the proper momentum.
As you get more comfortable and start going faster, you just up the amount of follow through.
I'm no Snowolf but that's my 2 cents.
so is hump/dump more suited for carving as opposed to skidded turns?
