Ummmm adding in your longboard experience is kinda mixing apples with oranges.
Longboards have a fairly flat rockerline from well forward of the mast track to the tail.
Short boards (and especially wide formula and early planing type boards) have a much different
rockerline with the transition from rocker to flat way back at the front of the front footstaps.
Lots of progressively increasing rocker forward of the footstraps.
So, if you do not get back on the board, and get the nose UP, you will constantly be trying to
get the board planing, with the flatter planing surfaces from the footstraps back actually lower in
the front. So until planing surfaces are inclined higher at the front, the boards nose is out of the water,
and the bow wave has moved back to the rocker transition under the front footstraps, the board will pretty much refuse to plane (negative rake to the planing surfaces).
Longboards are very different in this respect. Some of the transition boards, like the Rio's are a bit of a hybrid in this respect and while they do OK in longboard mode, they do not have the "glide" found in a traditional longboard or something like the Phantoms with the long flat rocker from the mast track to the tail.
