Max sponge of FL2 & 3 is only 1.3mm. Ilius S&B also the same.
Victas P series has 1.5mm sponge, and all topsheet has good friction.
Ease of creating backspin in short game: P3av/P4v > P3v > P1v
P1v requires higher power to generate backspin so not easy for short game. But away from table you got space to do full stroke to generate backspin.
P3av/P4/P3 can do backspin push rally if you got proper technique. Threshold is much lower than with P1v.
Blade with longer dwell time can also be helpful.
Example: when I used BTY JSH & P1r 1.5 10yrs ago, sucessful rate of create backspin push was really really low; Since I switched to Nexy JSH1 & P3av, the amont of backspin push surprised my opponent quite often. Besides technique, Nexy JSH1 has much softer top layer which helps catch the ball, just like what Joo said in the promotion video.
About how to add backspin with LP, Joo has explained well in this vedio:
starting 7:51
Another thing I sensed but not quite sure is, the way to do backspin push with FL2 & Ilius is to use pip top but not the pip side (or the pip floor). Try it out and see if you can find the right way to activate it.

To deal with no-spin ball : above are all applicable, just the limit and outcome would be lower.
