Back-to-Back L/J-Spin Triple

Core Methods
You can use two pieces on either the right or left to create 1 J/L-Spin Triple. Using different methods, one can stack as many as he/she likes. Notice that the cores are interchangable.

SL and ZJ Cores
These setups use a good balance of pieces.

OJ Core
The weakness of this build is that it uses a poor balance of pieces, including J's or L's which can be used otherwise for the Triple.

The Comfy Chair (LSO Attack)
This is arguably the safest method. It uses the least amount of pieces giving seven open columns to stack freely.
