I am looking to cancel a few cards in prep for a yearly churn ; I wanted to get some insight from my FT family and see what y'all think of the Chase CO card...shold I keep it or cancel?

I got shafted with this card because I got nailed with an $85 annual fee, which I didnt win the email fight with, and I only got 25K miles as a sign up bonus + 5000 for adding another user (standard op procedure at CHASE these days).

Ive had the card now for over a year (just got the two presidents club passes)...I took full advantage of this card and used the Onepass mall for Xmas purchases and cell phone bills, coins, etc....racked up almost a good 20K miles on it. If I cancel, any chance of rentention miles? Any advice?
