What determines the reversal of long pips?

What determines the backspin that long pips can generate? Is the equipment or stroke more important (assuming you are chopping the same ball)? Do you get more backspin if you have more of an active stroke than a passive stroke? If your equipment can generate more spin, does that mean it has less reversal (slick ox on a stiff hard blade vs grippy sponge on a soft flexible blade)?

I always think stroke is more important than equipment in generating spin. For L.P. passive strokes less grippy rubber has less reversal but with active strokes trippy rubber generates more spin, or trying to topspin your opponent a topspin. Active chopping a topsoil ball-I am unsure.
