I only majorly disagree with one thing I read

Limiting your pattern choices by avoiding jacks severely limits your work, especially for 4-key, where you don't have a lot of room to begin with. By incorporating jacks into your patterns, you not only have more options, but these jacks will add a lot of expression into your work.

There's a lot that can be done while avoiding misc jacks and such.

Still a great guide either way.
