Listen to earlier KT with Dave Guard or John Stewart doing the banjo duties. they play a style of T-I,M that takes on a likeness to Seeger picking. Or use the Seeger style and develope your own likeness. TIM is Thumb, Index, Middle finger rolls. Lindsey Buckingham's guitar playing is a likeness to John Stewarts banjo riffs.
My strongest advise about any style is make it your style. Practice the rolls, strums but adapt them to your own feelings and don't immulate note for note what Pete Seeger, Earl Scruggs does. Find the Don Meixner style of playing.
My finger style of Guitar playing comes from attempting to learn Bluegrass rolls and through some frustrations of failure, use those rolls to play guitar. The playing of those patterns and finger rolls are a mix of everything and has developed from many many hours of repetitious practice. The results are noticed when you relize what you do with the banjo comes natrurally and like walking, you just do it with out giving it a lot of thought to it.
If you watch a lot of TV, sit in your chair, dead the strings with your left hand and riff those right hand fingers with all the practice you can without making alot of noise, then at commercial break kick ass with the three to five minutes of commercials. Then apply those techniques to the music you want to play when you do your real practice time. Those are some hints at some things I've done to harness my skills. The banjo does'nt really play the same as guitar by leaving a chord pressed on, it seems to me the left hand gets as busy as the right making it a much more difficult instrument to learn. The bottom line is DON'T GIVE UP. Whatever you put in to it, it will give back many times over. Good pickin' to you
