Do a search for "Rcr123 battery shootout silverfox" and look through the first few threads to learn about the battery test and which had which qualities. That should help speed you on your way.
I must say that CPF preference is AW cells over in the Marketplace, however do your research and make up your own mind on which you wish to run.
