Trapeze is a first bag TSS opener created by 10Penta that has multiple continuations.

First Bag

The first bag has a 56.7% build chance including mirrors, and requires early L/J. Usually, you should mirror depending on whether S/Z comes first, but in rare cases you may have to mirror depending on whether L/J comes first. I can be spun in after everything is placed. TSS can be taken either horizontally or vertically.

Second Bag TST Tower Conts

These use horizontal T. First conts to be created, labbed by 10Penta. There are 2 routes.

Route 1 Main Route (O/J < T/S/Z)

This can be built 90% of the time, and has an 100% 3rd bag.

Route 2 Compromise Route

This can be built if the main route cannot be built. There are 4 congruents, but only the 3 below are required to cover all bags with the main route.

There are a lot of ways to build the 4th bag. There is a 4-min set that covers all bags, but some of them are not clean; it should just be freestyled. Below are some ideas.

2nd Bag Long DT Cont

Credits to Ivan for discovering this. TSS is taken horizontally. The following bags are all 100%:

2nd Bag DMTD Cont

This cont makes a TSD then TSM into a C-Spin. TSS is taken vertically. LJO interchangeable. Z is held. 1st image is O<L, 2nd image is L<O. TZ can be spun in for L<O after ILO are placed. 4th bag is freestyled.

2nd Bag 8L Conts

Trapeze also has relatively good 8L PC chances.

L<S 100%

This is after horizontal TSS. This has a 99.96% PC chance after the TSD, and the 2 fail queues ([IJ]!TLSZO) are covered by the TSS and also guarantee another TSS. Minimals can be found here.

All Bags 98.3%

This is also after horizontal TSS. Taking the TSD lowers the chance to 90.6%. SFinder died while running minimals hold T, so minimals after TSD can be found here, and a not very minimal set of minimals for hold T can be found here.

2nd Bag DT-PC Conts

These conts do not cover all 2nd bags, so you will need to use something else to cover the fail queues. They are both after Vertical TSS.

Variant 1 L<S

After the 2nd bag, you have a 96.5% chance to get an 8L PC with T on hold, or 87.3% if you take the TSD, with 26 minimals. Otherwise, you can freestyle a TST or Incomplete TST. If you have S<L/J (3rd image, LJS rectangle interchangeable), then you can build a TST with a 44.3% chance to get a 10L PC with T on hold, or 39.9% if you take the TST, with 15 minimals. Otherwise, you can always build the 100% TST setup. If possible, delay the TSD to combo with the TST.

Variant 2 O<L/Z

Similarly to Variation 1, you can freestyle a TST or Incomplete TST. However, you do not have an 8L chance. If you have S<J (3rd image), you can build a TST with a 63.2% chance to get a 10L PC with T on hold, or 56.2% if you take the TST, with 44 minimals. Otherwise, you can always build the 100% TST setup. If you want to avoid a gravity wait for the O piece, you can place the J piece differently or switch the positions of the J and O. Again, if possible, delay the TSD to combo with the TST.

Freestyle Conts

Horizontal TSS easily continues into 4-5, and vertical TSS easily continues into 3-6, so it’s very easy to freestyle after the first bag.
