Second Bag
If one cannot make one of the above stacks, try one of these stacks. The first seven stacks can result in a Perfect Clear.
Alternatively, one can convert it to a Center 4-Wide with six residuals.

Below are solutions where a T-Spin Double can happen beforehand.

After 3rd Bag PC
After a 3rd bag Perfect Clear and an O is left unused, one can use this technique afterwards.

In the fifth bag, there are various solutions, so memorize the ones with S and Z being used together.
