I am pleased with the SL BofA gave me. I think it's very generous of them. I guess all that time with them has paid off. I have a similar relationship (time-wise) with Wells, though I don't put nearly as much money through my accounts w/ them. I might give them a try and see where it lands me. In the meantime, I'm focused on NFCU. So far, aside from the funding accts issue, I like them very much. I can see myself sticking with them for the long haul.
Update:
After being approved for AMEX BCE w/ SL of $5000, upping my CL on my Redstone secured card to $5000 and adding a NFCU $5000 SSL, my Fico8 scores are as follows: EX 733 (FICO8), EQ 705 (FICO 8) and TU 733 (FICO 8). I took a small hit on EX for the AMEX HP. The NFCU SSL is reporting balance @ $5000 (even though I paid it down to $445 same day). No hit on that new line reporting (yet).
I'm OK with this. Definitely pleased with where I am right now in this journey.
