looking at possibly getting rvp or motion pro. has anyone used one or the other. any thoughts. 2nd question, i see you can you can buy some of the rvp instruction cd's as a stand alone. does anyone know if some of the clips in the rvp instruction cd be used in the motion pro. the motion pro is so much cheaper than the rvp. was looking at maybe buying the rvp drills and using the motion pro software to save money.
