SP should be easy against a loop. Your 2 options are to (1) block it back or (2) flat counter-hit back. Third option
Both shots are played in a similar way. Take the ball just after the bounce for both - don't let it rise too high. For the block, with 802-40's spin properties, you will need to close the blade a little, but play it with soft hands and you can send a controlled dead ball back with ease. Even better, counter-hit it - you don't need a huge action - just fast-roll the blade with your wrist from a vertical position towards being closed, over the top of the ball - do the action like a quick flick of the wrist. You can use that top spin to help you generate great pace, which will often be returned back into the net. I'm thinking forehand with this, but same should apply for backhand.
That's at least what I think I do anyway! Hope it makes some kind of sense!
:Drop back off the table and chop it. I do this with 802 with very good effect-more importantly Hou Yingchao and Ding Song are/were excellent at chopping with SP on the back hand.
For me, I am looking to chop a slow spinney loop to return to my opponent a lot of under spin. Then if he lifts it really soft and slow again, or dumps a bad push over the table. I am looking to crack in a winner off the SP's. I also twiddle some times if I think my opponent is going to push a heavily chopped ball back-twiddling is just not for defenders-He might be expecting a pips out loop and he gets a really loaded inverted loop. The danger for me is that I cant chop with inverted on my backhand at all, so I use this very
