I think the trick is to request a CLI after the 3rd statement with the Cap1steps cards. I plan on doing this with the QS1 card. Supposedly a $100 increase can be had at that time. Credit steps auto increases you after the 5th statement. I don't think you'll be eligible for another CLI until after another 6 months although don't quote me.
One thing you may want to consider is a Product Change or upgrade to the Quicksilver card to enjoy the 1.5% cash back rewards on purchases. You can call them to see at any time...or check online.
Congratulations on your CLI!
