From reading the thread I know everyone says a quick A --> B --> A cycling is not recommended. Can you add a reasonable pause and then reverse? For example, A to B for 2 months, no transactions for 2 months, then B to A for two months? Or does A --> B then preclude B --> A no matter the length of time?

I (A) no longer need AP for min spend while B now needs AP. We have no C. Thanks.
