Very very helpful! I'll refer to this post for awhile.thank you for all of that!
I learned a lot here within the past few months, so i am just trying to share what i learned with others. Barclay likes people that use the card and pay it off. I have talked to them a few times in defferent occasions and that's kinda what they told me, if i would be looking at CLI in the future. Synchrony bank gives good cli's as well. with them never be shy to ask high. It is one bank you aim for the stars and shoot the moon 
Congrats
Do not open anymore new accounts. You have enough for now. You need to let them grow and age. Personally I would wait 6 or more months to get a new card. Now to correct some misinformation that was given to you. If you do not use a card it will not lower your AAOA. If it is closed for any reason it will not affect your AAOA. Fico 8 includes closed accounts in AAOA. I would suggest you keep your accounts open for at least year. If you close them so soon it will not look good to other creditors when they look at your credit report. There are others on here who can chime in on how to rotate to keep accounts active. Looking at your cards and the fact that you have a teenager in the house I don't think you will have a problem keeping them active.
