Ball pocketing vs. Top spin

I recently heard the Tennis Warehouse podcast about classic racquets (here) (which was really good by the way), and it really made me wonder how ball pocketing (or as some of the playtesters say "plush feeling") affects topspin generated by a racquet. I understand the science behind how, when using the same string setup, a heavier racquet can pocket the ball more, and the spring effect can generate more power. But I'm not sure what effect, if any, this has on topspin. Anyone have any insights?

For a broader picture, I'm wondering about this as I'm thinking of developing my game, the type of player I want to be, which areas of my play to improve, and eventually what sort of racquet I want to play with. I'm a 3.5 level player (at least I was at the beginning of the year before quarantine) and am playing with the new Yonex vcore pro 310 which I've weighted up a bit. However, I tried the new Yonex ezone 98 last time I played and really enjoyed it. But in my mind, the type of player that can fully (or to a large extent) make use of a vcore pro is different from a player that can make use of an ezone. Not sure how to consolidate these two preferences.

Formula for power is mass X acceleration pocketing is more a response of string spin has to do with the angle that the racket is going vertical 60 degrees needed for top

To generate spin, what you need from a racquet is "grabbiness" © . Grabbiness© , combined with a high racquet speed, produces the sensation of pocketing.
Other than this, I do not think they are related at all. You can have a soft racquet/soft strings with tons of pocketing, but useless for spin. Stiff racquet/lack of pocketing is not guarantee for spin either. Lots of racquets out there with "slippery" stringbeds. It is mighty hard to generate spin with. Pocketing is just a sensation, after all. More of an aftertaste than an engineering concept. Impossible to measure of model.
Best pocketing <= soft racquet + soft strings + hitting flat. Pleasant, but not for competitive tennis.
Best spin <= stiff racquets & super stiff poly, very sharp-angled face on impact (Nadal)
Two completely different directions... One will have to be sacrificed...
