I would say it's worth a shot; since the approval is computer generated, there may be $$$ left on the table. Example: bro got Lowe's @6K w/ thin file 681 EX. Called in as soon as the card came. Requested 35K, approved 35K. I personally received 1K auto CLI on my Dick's ScoreCard after less than 2 months. Hadn't found this awesome forum yet back then, so didn't know that you could request a CLI. Would have liked to try it and see if this one is capped @ 35K too 
worst they can do is say no
