i was watching Oprah once a long time ago (before i had a day job) and she talked about doing a "box test" with your kitchen. the idea was that you put all your utensils in a box, and only take out what you need when you use it. put used utensil in the drawer. after a month, whatever wasn't used (still in the box) was to be discarded. perhaps you should do that with your basses. put them all away somewhere, and only get out what you need. after a month (or two), whichever ones are still in storage get sold.
