What do you know about velocity banking strategy?

[Tyler Shane Martindale]

I recently heard of something called "velocity banking" where you use a credit card to pay off large portions of your mortgage or other loans, then use the credit card balance like a checking account. The idea is that the credit card is more controlable because it is not amortized, and the strategy supposed to help you avoid paying as much interest on front-loaded loans.

Is anyone familiar with this or used it before? Did it work for you? What did you learn? What can you share with us about your experience?
