Because of my limitations of living in an aparment, I usually can not hear what is listed on the clusters. I like using them myself so I can at least tell what band is open. If I do hear a pile-up, I will try to work it. If I get in, I get in. If not, there is always someone elsewhere in the band that I will be able to work. It really depends on if you want to use the clusters only for your contacts or use it as a tool that shows you what bands are doing what.
