I think the Wes Mallot video is very interesting. One could even say "Fingers below the equator is over-rated", by itself. If you look at Malott, his is right at the equator.
I was talking with a friend of mine (a while back) about theoretically altering the equator of a ball. My agruement was just having your fingers at a position isn't enough to create serious spin or revs, its more of a total picture as far as where you start and where your fingers finially exit the ball and what that distance is. You can put on a brace and set it to cup the ball (and you will create more revs) but cupping the ball then unloading at the release will create even more revs because the distance your fingers stay in contact with the ball is longer.
From a 90 degree angle (looking at the hand position), a cupped hand will sit approximately at 6-7 o'clock and exit the ball at 9 o'clock while unloading will take it a little further to say 11 o'clock. More revs, longer overall distance spent with fingers in contact with the ball. The goal then should be 12 o'clock for maximum revs? No. You need that distance from 11-12 for the last part of the release. That i believe is where "slapping" the ball comes into play. Accellerating your followthrough only helps to maximize this slapping of the ball. Slapping can't be up behind the ball, it must be over the top of it. If you're slapping up behind the ball, then your stealing revs from peter to pay paul and there is no gain in that.
Now back to altering the equator (for the better). Lofting the ball to any degree will never get anyone the revs someone who drives
through the ball will get because they have a "Flawed" equator relative to the optimal plane. Any of these video's above will show drive, not loft. Lofting is anything other than optimal (unless we're taking about dropping and thats a whole different problem). Working towards that optimal plane will maximize this area of your game.
Lets not forget working the inside of the ball. Its not only putting your fingers in a stronger position but its allowing your fingers to stay in contact with the ball a longer distance (curve being longer than a straight line from point A to point B) because you're not going in a straight line.
So, to create revs you need a longer distance with as short of a time you spend there as possible while maximizing leverage in all areas.
