For me the term rev leverage is actually one i use to use from ebonite sorry, lol. some habits die hard. it's pin in a leverage position, with the pin below ring finger and cg and MB are in strong position, but below the thumb, so it's leverage and creating a slightly early roll.
basically 3 3/8 x 3 almost, but it's pin below the fingers and cg closer to thumb, i prefer to use longer pins 3-4 on rev lev layouts.
early roll, lots of hook and strong finish in the backend.
