Your bat may not be open enough; open it a bit more. Or your stroke may be too passive, in which case the strong backspin on the ball is reversed into strong topspin so the ball quickly drops - on your side of the net; you should be able to see whether or not this is the case (look at the ball when it hits the net - if it stays there or tries to climb it, there is strong topspin on it), and if it is, make your stroke more active: much quicker but not much more forward, a little bit more up (scooping).

I've found dtecs to be very bad at pushing backspin. The only way I've found to make this work is taking the ball just after the highpoint. If I try any sooner I have to hit it

I find Dtecs is excellent for pushing backspin. The stroke is probably different than you are use to, bare with me while I try to explain it.

You want your bat head to be oriented vertically, and lead with your fist. It definitely feels weird, but if you do this and have the correct bat angle, you will find pushing backspin with Dtecs is not only a lot easier than you thought, but when you get feel for it, it can be an extremelly dangerous shot. When you do these things you can push the heaviest back spin with very little effort, instead of having to push really hard to counter the heavy backspin. Additionally, this is more potent the closer you take the ball to the bounce. (Also, obviously if you are leading with your fist you cant take the ball immediately off the bounce, but pretty close.)

Because of the speed and liveliness of the Dtecs. I find this shot to be not only the really easy to perform, but also more dangerous relative to other LP rubbers. (I think this shot is a good example of how Dtecs can be a lot more dangerous compared to other LPs that may be easier to use.)

I am not sure if this stroke has to do with the pip orientation or just the mechanics of your arm, but when doing the correct technique it seems effortless.

(I will add that for almost the last month I have been playing with P1r and and this stroke pushing backspin might be the thing I miss about the Dtecs the most compared to the P1r)

Can you translate the stroke into a penhold vis shakehands stroke for me?

Unfortunately I am afraid I cannot. I don't play penhold so I cant speak to that, :/ sorry.

when you are making the stroke which do the pimple align. I can translate into angle for penhold.

what angle is the blade?

What kind of line or arc does the blade describe as you are making the stroke?

Maybe I can put those pieces together
Thanks

What determines the spin on the ball after you make contact with the ball using long pips? Is it the stroke that you use or the spin that your oppenent put on the ball?

Both. Some LPs can create spin more than others depending non how grippy they are. But some LPs are very slippery and some are very grippy (for an LP).

For example, with sponged p-1r. If I get underspin from my opponent and push it back using an inverted style horizontal push, I can send back no spin or slight underspin depending on how vigorously I brush the ball. If I do a flat hit or roll I can send back a dead ball...light top...or moderate top if he gives me enough spin to work with, and depending on how much I brush the ball.

What stroke (aside from the chop) and type of long pips should i use to maximize underspin against topspin?
