Hi Martink,
Yes your absolutely right, there’s no real black and white difference between a drive and topspin and sometimes it can be something in between as you said. There actually isn’t a huge difference between a backhand drive and topspin technique, its just the bat angle and the way you contact the ball really. Both use the wrist although the topspin slightly more so.
I can’t view the link you sent for some reason, but again totally agree with you that high level players are almost always using backhand topspin shots, even close to the table. That’s because it makes it much harder for an opponent to return if the ball has topspin and kicks towards them quickly.
So just keep working on improving the backhand topsoin close to the table especially and using more spin, it sounds like you have a pretty solid backhand which can keep improving!
