Its true that they are more styles that just the two I mentioned. Clawhammer and its variants, and 3-finger, plus its variants, are the main groups of styles.

You may be able to get a pleasant sound by using guitar fingerpicking technique on a banjo, but its not really banjo playing. Using a pick on a five-string is so wrong I cannot even begin to explain. A six string guitar-banjo is neither.

Its easy to do some real investigation by looking at youtubes. Please dont be in a hurry.

I already offered to talk further over phone or Skype or whatver ya got.
