Welcome to FT, OP.
As always, I would like to bring a new twist to the recommendation - How about WN RR Cards from Chase:

The cards are not good for everyday usage. However, if you can get both RR Premier and Plus cards (50K+50K) together, you will be very close to get a CP (110K).
Since you can achieve more with these 2 cards than the CSP. I think you should think about it.
The only bad news is they both carry an AF that are not waived.
