Most likely thay will use the same HP for the next 30 days so go ahead. The only thing that I can see stopping you is lack of Penfed history.
Good luck and congrats
Congrats to you..
I believe you would have better luck on a second card after some history with them.
My SL was $10,000. 4-5 months ago and I haven't tried for any CLI or second card yet- I believe like NFCU, they give you the max they're willing at first and will raise that in limits & other products after some history.
It's obviously up to you..
