I am working on the darn N1 review and wrote the below. Any one have any thoughts? (it is a first draft so spare me about any typos)
The two definitions of a fast ski are “a ski that achieves width with less than optimal rope tension from the second wake out” or “a ski that requires less physical strength and effort to get from side to side”. Generally speaking fast skis tend to be finicky at the apex of the turn and are less stable approaching the ball. It is assumed that a faster ski literally ride higher in the water.
Slower skis are often described as having a more stable and tactile feel approaching the ball. Especially at 34mph slower skis require better management of rope tension to achieve width and more strengths to get from side to side.
