This page discusses Continuous Twisting Setups, meaning setups that can go indefinitely forever while keeping the B2B reward for Twists.
This is a continuous twisting setup created by player WeepingAngel. It allows for a flexible variety of pieces leading to fast attacking, and is also a wonderful aesthetic rewarding to the heart. It can lead into ZST/SST Stacking or one can even throw a few in and continue doing Other Spin Doubles.
 Basic Shape
The shape needed here is essentially a 4-wide gap with 1 block in either corner. Making the foundation is identical to that of ZST/SST Stacking. Check the link below for more information.
 Setting up the Attack
This setup depends heavily on your next pieces. You must look ahead.
This is a Continuous Twisting Setup. Note that one does not have to wait for the "Lid" or top piece to perform the spin. Try to put in the S or Z as soon as you can. See Order section below for example.
