First is an opener with a series of TSS > TSD > PC/TST setup by shenmirenwu3112. This opener requires S or Z before T and O. The way(direction) to do this opener depends on L and J. The example below is L before J. You can use the 180 spin to tuck the J in.
Tspin single 
Residue 
Variant 1 SDT
This variant requires O before L and L before S


Sometimes the T piece might come early and you might not be able to build it like this. You can place the T first to skim it first.
98.21% PC chance
This variation has 9 minimal solutions, all of which are shown below.









3rd bag Tspin triple route: You just need to place the I piece and Z piece like below, or freestyle it on your own.

This setup will be used as an example. The shape is same as variant 2's TST route as well as the solves after.



Another TST route if you cannot build the TST setup like above. When you have late Z and early T with a ILOSJ queue(L earlier than O and S):


This setup is same as Variant 3's TST route as well as the solves. Just look there for the solves.
10 height PC (13.10%)
You can do a 10 height PC after the TST route like this:



14 height PC
Var 1(49.84%)
You can build this setup and do a TSD. This setup is only 100% with 180 rotation to tuck the J in.


Then the 14 height PC:



Var 2(89.68%)
Similar to the first variation, but much more higher chance of PC. You can always stack this way.


Then the 14 height PC. It has 5 minimal solutions:





Var 3(94.33%)
You can do this setup if J comes before Z:


Then the 14 height PC. It has 7 minimal solutions. All solutions are shown below.







Var 4(95.79%)
You can do this setup if J comes before Z:


Then the 14 height PC. It has 6 minimal solutions.






Variant 2 SDT
This variant requires early S and L (S before L) or early Z and L with S before O.


Below is early Z and L with S before O. You need to softdrop the S and rotate counterclockwise




Sometimes the T piece might come early and you might not be able to build it like this. You can place the T first to skim it first.
97.74% PC chance
This variation has 14 minimal solution. The common solutions:

3rd bag Tspin triple route: You just need to place the I piece and Z piece like below, or freestyle it on your own.

For my example, I will use the below setup or you can just freestyle it. The second build requires I before J. This setup has the same shape as variant 1's TST route.



Another way to stack TST if you cannot stack the way like above, when you have late Z and early T with queue JOSLI (L later than S):


This shape is same as Variant 3‘s TST route as well as the solves.
10 height PC (13.10%)
You can do a 10 height PC after the TST route like this:



14 height PC
Since this shape is same to variant 1, I will just show the setup with the highest PC rate of 2 different setups.
Var 1(89.68%)
You can always stack this way.


Then the 14 height PC. It has 5 minimal solutions:





Var 2(95.79%)
You can do this setup if J comes before Z:


Then the 14 height PC. It has 6 minimal solutions.






Variant 3 SDT
This variant requires early Z and L.


Sometimes the T piece might come early and you might not be able to build it like this. You can place the T first to skim it first.
96.03 % PC chance
This variation has 8 minimal solution. All solutions are shown.








3rd bag Tspin triple route: You just need to place the I piece and Z piece like below, or freestyle it on your own.

For my example, I will use the below setup or you can just freestyle it.



10 height PC(26.11%)
This setup has 9 minimal solutions. The common ones:





Full minimal solution here: Link[1]
14 height PC(84.52%)
This setup is 100% buildable:


Then the 14 height PC has 6 minimals:






14 height PC save J(99.78%)
If J comes late or you manage to save J:


It has 12 minimals, the ones below are solutions which can be stacked above 25%:

Miscellaneous
2 Line PC
You will have a small chance to do a 2 height perfect clear if you manage to save O after performing a 8 height PC and not more than 1 piece among TSZ comes before all of ILOJ :



You can follow this up with what is known as a TSZ 7th PC. Just search it up if you are curious about it.
Hold S in Variant 1
Sometimes you will want to save S when doing Variant 3 and this will have a 100% PC chance after TSD.


Alongside the PC chance, this leads to 5 minimals.





Alternatively, you can go for TST or anything else:
