Hey Captkirk!
My bro got the pre-approval offer from them for ultimate Rewards Plat. His score: 671 - EX- 45% utility- 4 years history but very little with cc. He was approved for 3.5K. I was surprised. I have found the lending criteria for true pre-approved offers to be a little more lax then hard apping a card. YMMV thou! Good luck!
Starting Score: 642
