i would stay away from fiberglass antennas. you were on the right track with the Wilson 2000. steel whips will always out perform a glass antenna any day as long as you have them tuned properly.
as far as Barjan buying the Wilson brand of antennas is just a myth.
if you look at the packaging you will see the Wilson brand on there and not the barjan.
i do know that barjan just bought the teletex road kind brand of mics but nothing has come out for them buying the Wilson line of antennas.
also for some great information check out
www.cbradiotalk.com
a lot of good information there and you will learn a lot of stuff on there too i know i have.
