don't go overboard in the first 6 months with the card, make payments more than minimum, don't be late on any credit account you will be fine, don't go over 80% usage on cards, if they collect interest on you, they will love you, they won't give you CLIs but they will have no problems collecting the interest, pay it down when you can.,
You should always aim for PIF. Chase will love you even when you PIF.
Most people seem to hit their limit with Chase after 3-5 cards. I'm not sure how they calculate the actual dollar amount, but most seem to approach their limit by then.
I'm not sure what Chase's ceiiing is for CLs. i have two accounts with them - a JP Select with a $25.000 CL and a CSP with $20,000. I have no other relationship with them other than these credit cards.
