Board length is largely preference but weight is the primarily factor that will determine how a board responds to you. Height is largely irrelevant.
For a given model, the longer the board, the stiffer it is and as such can support a heavier rider. There is lots of room for error if you are not carving. If you are... on a board that is too soft it will be overwhelmed and will frequently lose an edge in all but ideal PP. The harder the pack of the corduroy and the higher the speeds involved, the greater edge hold required to hold a carve. Greater edge hold is gotten by a longer effective edge....in other words, a longer board. A soft board will also suffer from chatter at high speed. A very stiff board will be unable to carve effectively at low speeds. Shorter boards require less effort to pivot or rotate. Park riders will typically opt for the lower swing weight.
