Right now I'm working on my 110,000 points, and am on track to hit my first 50K bonus in 2016. But with the holidays I'm also trying to hit the shopping portals. I'm a newbie here.

Ultimate Rewards seems to give better points-to-dollar ratios than Rapid Rewards. Do you always use your Rapid Rewards card on that portal, and your Chase Sapphire (or other UR card) on that portal? Can you ever cross over? It doesn't seem like you could, but thought I'd ask.
