Setspin

Setspin is a 1st bag TSS opener created by 10Penta. Its main continuation is a TST Tower, which can always be executed on the 3rd and 4th bags, unlike most other TST Tower openers. There are also Incomplete TST and LST continuations.

First Bag
The first bag has a 63.3% chance to stack the first bag including the mirror, and a 43.3% chance not including mirrors.

TST Tower Continuation
There are 2 setups that cover the 2nd bag with LJO interchangeable:

You may need to use hold.

Route 1 Z<T
The first image can always be built, but the second and third may result in a flatter stack:

10-Line PC Chance
If you can stack like below, you have a chance for a 10-Line PC:

You now have a 12.62% chance to PC with 4 minimals, with a 7.6% chance for a TST solve:

Route 2 T<Z
There are 3 good ways to stack bag 4. The last one is messy so avoid it if possible, but it may be required.

C-Spin Follow-up
After most TST tower setups, it is possible to build a C-spin follow-up. Below is an example after the flat Z<T setup:

Incomplete TST Continuations
The following continuations, created by 10Penta, build an incomplete TST followed by an Imperial Cross, TST or TSD into 14L PC.

Route 1 O<Z
L and J are interchangeable. There are many good ways to build an Imperial Cross on the 3rd bag, the setup below covers all bags with the JLS interchangeable:

10-Line PC Chance
If you have I<S, then you can stack as below for a chance for a 10-Line PC:

You now have a 67.6% chance to PC with T on hold with [https://harddrop.com/fumen/?v115@fgB8zhh0E8hlwwg0H8xwG8glwwg0G8glH8ywH8wwE8?JeAgWYAR4P9AFbcRAyv78Aw3CwBFbEwC0i3LCfgB8Bthlh0?E8Btglg0H8glg0G8ywG8wwH8ywH8wwE8JeAAPXAZVuRASo7?8A1no2AlsCSASYVxCqiDCAfgB8BtzhE8BthlH8wwglG8xwg?lG8wwH8ywH8wwE8JeAAPXAYleRASo78A1no2AlsCSASYVxC?sndBAfgB8BtzhE8Bth0H8g0glG8ilG8wwH8xwg0H8wwE8Je?AAPXAYleRASo78A1no2AlsCSASYVWCqndBAfgB8BtzhE8Bt?RpH8RpG8ywG8wwH8ywH8wwE8JeAAPXAYleRASo78A1no2Al?sCSASYVxCvndBAfgB8BtzhE8BtRpH8RpG8ilG8glH8ywH8w?wE8JeAAPXAYleRASo78A1no2AlsCSASYVWCvndBAfgB8zhR?4E8hlR4H8RpG8glRpG8wwH8ywH8glE8JeAAPXAV1gRASo78?A1no2AlsCSASYdgCMddBAfgB8Bthlh0E8Btglg0H8R4G8R4?g0G8wwH8xwglH8wwE8JeAAPXAUVuRASo78A1no2AlsCSASY?9tCqiDCAfgB8ywilE8i0wwH8xwG8whg0wwG8whH8wwwhglH?8whE8JeAAPXAUFjRASo78A1no2AlsCSASYNMCqC2BAfgB8z?hh0E8ilg0H8R4G8R4g0G8wwH8glxwH8wwE8JeAAPXATVuRA?So78A1no2AlsCSASY9tCqSdBAfgB8ywilE8wwi0H8R4G8R4?g0G8wwH8xwglH8wwE8JeAAPXATVuRASo78A1no2AlsCSASY?9tCqOkBAfgB8hlRph0E8glRpg0H8R4G8R4g0G8wwH8glxwH?8wwE8JeAAPXATVuRASo78A1no2AlsCSASY9tCqyqBAfgB8h?lh0R4E8glg0R4H8RpG8g0RpG8wwH8glxwH8wwE8JeAAPXAT?VuRASo78A1no2AlsCSASYdgCqyzBAfgB8Bth0R4E8BtR4H8?RpG8g0RpG8wwH8ywH8g0E8JeAAPXATVuRASo78A1no2AlsC?SASYdgCz3fBAfgB8hlRph0E8glRpg0H8wwg0G8ywG8wwH8g?lxwH8wwE8JeAAPXATVuRASo78A1no2AlsCSASYVxCqyqBAf?gB8zhh0E8ywg0H8R4G8R4g0G8wwH8ywH8wwE8JeAAPXATVu?RASo78A1no2AlsCSASY9tCqedBAfgB8i0ywE8zhH8R4G8R4?wwG8g0H8ywH8wwE8JeAAPXATFjRASo78A1no2AlsCSASY9t?CpufBAfgB8ywglh0E8ilg0H8R4G8R4g0G8wwH8ywH8wwE8J?eAAPXASlwRASo78A1no2AlsCSASY9tCqC2BAfgB8i0ilE8z?hH8RpG8g0RpG8wwH8xwglH8wwE8JeAAPXASlwRASo78A1no?2AlsCSASYdgCp/jBAfgB8ywAth0E8hlwwg0H8xwG8glwwg0?G8glH8wwBtH8AtE8JeAAPXASlwRASo78A1no2AlsCSASYVW?CqX2BAfgB8hlzhE8glRpwwH8xwG8RpwwG8wwH8glxwH8wwE?8JeAAPXASlwRASo78A1no2AlsCSASYVxCvSdBAfgB8i0ywE?8BtQ4wwH8R4G8BtQ4G8g0H8ywH8wwE8JeAAPXASleRASo78?A1no2AlsCSASY9tC6ufBAfgB8i0ywE8Q4g0xwH8xwG8ilG8?glH8R4wwH8Q4E8JeAAPXARlwRASo78A1no2AlsCSASYDxCz?ufBAfgB8i0ilE8RpAtwwH8xwG8BtwwG8AtH8RpglH8g0E8J?eAAPXARlwRASo78A1no2AlsCSASYlFDvifBAfgB8ywAth0E?8wwBtg0H8R4G8R4g0G8wwH8ywH8AtE8JeAAPXARlwRASo78?A1no2AlsCSASY9tCqX2BAfgB8i0ywE8RpxwH8xwG8ilG8gl?H8RpwwH8g0E8JeAAPXARVlRASo78A1no2AlsCSASYDxCvuf?BAfgB81wE8i0wwH8RpG8whRpG8whH8wwwhg0H8whE8JeAAP?XARVcRASo78A1no2AlsCSASICMCqO2BAfgB8ywAtR4E8zhH?8R4G8ilG8glH8wwBtH8AtE8JeAAPXAQVlRASo78A1no2Als?CSASY7LCzX2BAfgB8ywAtR4E8hlR4H8RpG8glRpG8glH8ww?BtH8AtE8JeAAPXAQ1gRASo78A1no2AlsCSASIKWCzX2BA 29 minimals].

Route 2 Z TST made by seacucumber (OLJ interchangeable); There are many ways to build the TST, the two setups below cover all bags.

Route 3 Z<O, L<J
There are TST continuations here, but most of them are messy, so freestyle is possible or the TSD 14L below:

You now have a 99.46% chance to PC with T on hold with 12 minimals.

Alternatively, on the 4th bag, you can setup this STSD with OSZ interchangeable (by winterfrost):

LST Continuaton
This LST Continuation, discovered by ADT, requires L<S:
