I don't mean to be rude, but I don't think you know what you are talking about here. The benefit a knuckleball gets from its lack of spin is unpredictability in its movement and not movement itself. Outside of the knuckleball, breaking pitches (i.e. pitches with the most movement) generally spin more than non-breaking pitches. For proof you can just take a look at the spin rate leaderboard[1]. Look how far you have to scroll down the list before you start seeing fastballs.
