Believe it is harder going cash back, but have heard of some holding multiples of the same CB card. Over here we run cash back cards as only 3% of total credit line available in the portfolio. That said, miles and hotel points are stacking like cordwood. Some of our spend is just to bump status now. We caught Hilton cheap skating us golds on upgrades in Tokyo to avoid executive lounge costs, so we are running up to platinum (executive lounge access mandatory) as a countermeasure, for example. Figure executive lounge access comprises 25% of the value of our Hilton stays so running up points for platinum status there is cost effective.

That said, I will probably try to bring CB up to 6-9% as a percentage of total credit line outstanding this next year to begin generating cash as an offset to ADK Jr.'s student loans. I am just a few countries short of this year's goal of reaching 150 countries (TCC countries) visited and have more than enough miles to reach it.
