Scores dont seem to move too much if you close cards but for one's own organizational mindset, it may be good to have fewer than too many. If you can manage a lot, go for it. I am in the process of having it so we have less. I also am batting around the idea of getting the types of cards with no preset limits. Example: Citi MC for AAdvantage already lets you go over the limit. NWA's WP Signature Visa lets you whereas the Platinum one I have has a 12k limit. I would like to have the ability to go beyond that. We also have Amex.
So in my mind, fewer is better, but get ones with high limits or no limits, and I don't think it changes your score too much to do the changes and consolodate.
