I'm trying to decide if getting the CO OnePass Plus credit card is worth it for me. I'm currently CO Silver and spend about $12,000 yearly on my one credit card. My one credit card is currently a Chase Freedom, which is basically no annual fee, 1% cash back on everything, with a few extra minor promotions here and there. I'd love to have a card that gives me miles instead of money, so I can save up for reward travel. But, correct me if I'm wrong, but the 1 mile per dollar spent doesn't really seem like that great of a deal considering there is also a $85 yearly fee, and the miles you earn from spending money aren't even Elite qualifying miles (I think). Is my Chase Freedom card with its 1% cash back and no annual fee simply a better deal? Or is there something about the miles and the extra perks of the CO card that make it worth getting?

Thanks!
Ryan
