eyyyy what a great session last night.
First want to say thank you to all the tips given.
I focused on 3 things last night, more diagonal stance when able to, more length in my swing and swinging from head down. Big difference.
The extra swing and head down made the biggest difference, my chops were closer to the net and longer on the table but more importantly had some serious backspin sometimes that even shocked me.

I also tried the wrist thing but my timing and consistency was so off I stopped after 10mins coz I wasn't getting anything from it at this time. Will try this when I am able to do some multiball.

I played against an international veteran champion and he commented sometimes my chops were really nice and heavy. So there is definitely progression

If your swing is longer, you'll automatically get more speed. That serves the same purpose as using more wrist. It's only, when you'll be an advanced player, you'll be able to do both simutaneously. Imagine the backspin on those balls!
