How old are the secured and unsecured cards you have? Its possible they simply havent started to report yet to EQ. I would contact the vendor of the cards and see if they report to all three. If they dont, you could ask them (worst they tell you is no). Capital One secured card will be a triple pull and will probably not graduate to a unsecured card. They sometimes give unsecured auto-CLI (Ive received two on mine) and you can deposit extra funds.
I would avoid cards like Wells Fargo, that report as secured, and typically dont graduate. We really need some more information on your CR's to give you some better ideas. What do you have on them now? Baddies, loans, CO/CA, BK, etc. What is your AAoA and number of inquiries? Do you have access to NFCU, USAA or other harder to get into Credit Unions?
Average Age of Account is AAoA.
You only need 2 secured cards so I would look at Cap1, Bank of America and maybe look into DFCU and see what they offer. Compare the three cards and pick one best for you. Cap1 is pretty forgiving in terms of approval but Bank of America is probably the best long term. (Note: with BoA you need to put down a larger deposit first as I recall they will HP you on subsequent deposits.)
