I could use some help - I'm new to this party and I don't want to make silly mistakes.

Some of my cards are coming up for renewal
Which ones are recommended to keep (pay for another year)
and which ones should I close out and re-apply for a new one?

Here is what I have (all have met their spending limits):

* MC AAdvantage
* V Club Carlson
* Ax SPG
* V Ink
* V Marriott rewards
* V Mileage plus explorer
