Honestly, just the other day I was considering going for the Slate because I wanted to BT around $7000 from my PRG. Actually applied for it, but it was denied because I had my Transunion Report frozen (no HP). I was expecting them to hit Experian. Didn't really want to unfreeze TU for them since I had 4 new HPs from last month. At that point I looked into the Citi Simplicity, which I found to have a better deal. 0% APR on purchases and BTs for 21 Months. There is a BT fee of 3%, so there's that, but for nearly 2 years without interest, I think it's well worth the 3%.
Applied for it yesterday and was instantly approved for $11.2K and a decent APR (after the intro 0% APR) of 16.24%.
With your scores, assuming they're true FICOs, I'd say you've got a pretty good chance for approval.
With your low # of inquiries I think the only issue would be your utilization. I've never had any experience with Citi aside from my app yesterday, although my utilization was 18%. That's the only thing I could see being an issue (at least where a larger CL is concerned).
In my case Citi pulled Experian but I've heard they like to pull EQ as well.
Let us know what you decide to go with
