TwinGhostKid, you are wasting your time. Go play and you will learn. Grip and wrist position will naturally adjust to different shots.
Wrist and grip are totally different for a fade loop, a straight loop and a hook. If you had to think about it, the adjustment of grip and wrist position would not happen the way it is supposed to. And if you adjust your wrist position your grip has to shift a little.
Pushing a ball with inside out sidespin will require a different wrist angle than pushing a ball with hook sidespin because it requires you touch a different part of the ball. Pushing a ball with topspin requires touching a different part of the ball than backspin so your wrist will also need to be at a slightly different angle. Add hook and inside out (fade) sidespin to top and backspin. You need to adjust to each ball. Dead balls also require you adjusting where and how you contact the ball.
Overanalyzing this stuff seems like it is making you more confused.
If the ball pops up, you touched top or dead as if it was backspin. If the ball gets pulled down towards the net or table, you did not get under the ball enough for the backspin. If the ball shoots to your left, you were too far on the outside of a hook sidespin. If the ball shoots to your right, you were too much on the inside of an inside out sidespin.
All these things happen as you play and over time; you don't even think about it; the brain processing of which spin and where to contact and how to adjust the grip and the angle, just start happening because you read the spin on the ball.
Trying to make it too conscious will mess you up because these things happen too fast for it to be consciously examined while you play. That is why you practice and do hundreds of hours of receiving serves and reading spin.
That is why, when someone is giving you a big hook loop, over time as you practice against that shot you get to be comfortable with a variety of ways to adjust to the hook loop spin. But the action happens too fast for you to try and turn it into a formula.
Practicing returning a pendulum serve thousands of times, hundreds of thousands of times, gets you used to the variety of wrist angles and contact points for the serves and spins that can come from a pendulum (fade or inside-out spin). Same thing for a reverse pendulum, hook, punch or tomahawk serve (hook sidespin). Any of those serves can be served, side, side-top, side-backspin or dead and varying degrees of any of those spins. So the actual key is practicing against each of those spins and getting used to how to touch the ball to return each spin. 1,000,000s of repetitions. And with any spin, there is always a variety of ways of returning the spin, including just smacking through the spin to knock to spin off the ball.
