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.
