Perfect DT (Perfect Double Triple/パーフェクト DT) is a setup invented by a Japanese player named Yuu. It perfectly resembles a TKI 3 Opening but with the J placed upright on top of Z which makes it look kind of like a "wing". Usually made to achieve T-Spin Double which could then be continued with T-Spin Triple without wasting a single T and usually ends with 8th row Perfect Clear. This is one of the only discovered setups that could achieve and 8th row Perfect Clear without wasting a single T (other setups like Albatross Special and Pelican could only do Perfect Clear after 10 cleared lines).This setup could be made with an early I and Z have to come before J.

T-Spin Triple
This setup is usually continued by T-Spin Triple. Notice how LI and JO could be swapped which increases the chance to score a T-Spin Triple without wasting a single T. It uses a very unusual overhang but it works nonetheless.
If L comes early but S comes before I, one could still create a T-Spin Triple with S placed vertically on top of L.
T-Spin Double
If it is impossible to make a T-Spin Triple on the second bag, one could still continue with a T-Spin Double. The chance to stack this one up is 100% because of how O,S and Z behave.
Here are the ways to stack up O,S and Z.
It is possible to continue the T-Spin Double with Type 1 ST Stacking.
Third Bag
After T-Spin Triple, there is 75,8% chance that it could end with 8th row Perfect Clear.
