Well it depends really, its all down to what your using it for.
If were talking codexl and all the fun that brings dont forget a lot are only valid when used in conjunction with alu interlocking lats.
We use 6 per section(48 total) with a proper qualifying load and only need two shoring lats across the back. And thats on 26t of beverages.
Id always use them, to be sure to be sure.
