I'm curious as to what your experiences regarding this matter are, since I experienced some extreme differences in difficulty of looping underspin when using the same rubbers on different blades.

So if possible I'd like you to share what you think are relevant parameters of blades that contribute to making looping underspin easier or more difficult.

Since your choice of blade influences the amount of 'dwell' in the rubber when you make contact, then it follows that different types of blades (in relation to structure or material) will affect the amount of spin able to be generated on contact, especially the ability to 'lift' underspin. Generally speaking, 5 ply blades allow more 'dwell' time on contact as opposed to 7ply blades. Of course, technique needs to be taken into account.

My observation is that it is much easier to loop underspin with a faster blade that is not very flexible.
The increased dwell time of 5ply allround blades means that the blade bends, and some power is lost.
So you need to swing harder at the ball to lift it, because energy transfer is not as efficient.

This sounds counter intuitive at first but makes sense imo.

If your opponent is Joo Se Hyuk your statement is correct but if you play with your regular player a 5 ply blade is more than enough to get the ball on the table and you can vary the amount of spin better than with 7 ply blade.

I tried playing a chopper with very flexy 5ply and low throw chinese rubber, which required huge amount of force to lift the ball, so I was figuring out what was wrong. I assume a stiff blade with high throw rubber will be the easiest setup for lifting underspin.

Huge amounts of force produce the highest quality loops. Even if you can loop more easily with something else, that doesn't mean the blade is the problem.
I like putting heavy topspin on the ball...

what kind of speed are you trying to produce against downspin?

In terms of spin, yes. But if you have to hit so hard that you are unable to control your speed and placement and also you have to have perfect position, then how is that not a problem. Maybe it wouldn't be in a world where everyone is superhuman.
