Query: short and sweet review of mogul skiing fundamentals

Nothing prepares you as much for mogul skiing as being on the hill. Nevertheless, this short book reiterates many of the lessons I learned on the way to being a better mogul skier. Hand and pole placement, weight distribution, spilling speed between bumps and pre-hopping are all covered very well. Illustrations in a book like this are never as helpful as video, but they certainly add.
