SDPC Spin, or Single Double Perfect Clear Spin Invented by Ecchou. This sends the same attack as Stickspin, but is simpler to build.

In all continuations, the first bag is stacked the same as the first bag of SDPC.

In all continuations, the first bag is stacked like so:

Second bag

Third bag

There are two ways to stack the third bag. The first is always possible, but the second results in a flatter stack.

If S comes before O, the following third build can also be stacked.

If the first build is used, the center area must be filled in to complete the T-Spin Double. This can be done freestyle or using the STMB Cave continuation below.

Taking the first C-Spin build

Stmb cave into Stsd

Created by Stickmancomic. This requires the first build to be taken for the third bag. J needs to come before L or Z in the first setup.

Alternatively, one can build a Trinity in the fifth bag, leaving cleaner residue. (100% build rate)

From here, upstack or donate a TSD.

Taking the second cspin build

If the Z comes too early, you can put the Z on top of the J piece.

Double Triple Cannon Continuation

You can build a DT Cannon with the residue after completing the C-Spin.

First build

Leads into 6-3 very nicely. Covers 91.67% of all fifth bags.

Second builds

Made by swng

O before L

L before O

Alternate fourth bag

If I is saved, there is a 68.10% chance of a 12 line perfect clear. Otherwise, you can transition into 6-3 or 5-4.

Taking the third cspin build

Early Z

An Imperial Cross can sometimes be built.

From here, you have a 99.68% chance of a 14 line perfect clear with 4 minimals.

Early O

Can transition to the second cspin build.

Early S

Can also transition to the second cspin build. Hold O and tuck it after taking the TSD.
