Congrats on the approval!
Too bad recon didnt work, but decent SL
Not sure if you can get the inq removed, but maybe can.
I would first try barclays to let them know.
Just not sure if 20 or 21 inq would mean much of a difference with scores.
You can try the HUCA, but be very careful if you do. The CSRs are really good at noting calls and results so you don't want to make them angry. I have read in other threads where someone managed to get a CSR who took a different course of action and granted a better SL. You need to tell them you're trying to buy a MacBook Pro or something along those lines and that you need a limit big enough to make the purchase. That helps.
