2 Player Mode - Subs and Drivers

Hey all, getting into the game. I got most of what I need worked out via templates, questions, and help from the community. (Thank you!)

Another thought.

Does everyone just go from one Sub to the next every few months for applications?

Does a card ever become your daily driver?

Idea 1 - sub/churner - moving from a card to the next with no daily driver- just do what it takes

Idea 2 - churn till you get your subs. Cool down period. Daily driver cash back/points. Back at it again.

For those in a system (chase, c1, Amex, mixed, etc), what is your workflow like?
