When my EX was around 650 or so I did the pre-app and was offered 3 cards each with a 3k CL.
I went ahead and app'd for the BofA Amex, but got the 7-10 day message. I called about 30 minutes later. They orig pulled EX (0 collections), but on recon they also pulled TU (1 paid collection). I ended up getting approved for 2k. The CSR was most interested in my 90 day lates with Sallie Mae.
When I was opted-out I only got the offer for the secured card. It took about 6 weeks after opting back in to get the 3 offers mentioned above.
I believe I'm one of the oddballs that received a lower CL than what was stated on the pre-app. After I had the card a month I requested a CLI (open-ended) and they took the card to 5k.
Good luck!
