Just got my Sapphire Preferred card in the mail today, boy is it a cool card...it's like made of metal reminds me of black card. It has a 8k CL on it as well, which card do you think I should try for a CLI first? And after how long should I wait???
I really suggest taking it easy for the time being.
You should be seeing a yellow box on PenFed when you log into your account soon. This is known as the Pre-Approved, or rather Approved box. It will offer you additional products and eventually a credit line increase option on your current card. PenFed gives very generous credit lines as they want to be your main card.
Chase will ALWAYS pull a new Experian if you request a CLI. Now, I opened a Freedom Visa Signature in 11/2010 with an initial credit line of $7,000 and in 8/2011 they gave me an automatic $3,000 CLI for a current limit of $10K. No inquiry and I didn't request it. So, use your card a lot, pay it in full and Chase will likley give you an automatic CLI even before the card hits a year. Of course, your mileage may vary from my own.
You have kept your nose clean all these years, so don't get caught up in all these approvals.
