Ken Gaines, a regular at Anderson Fair in Houston, Tx told me a sad tale. Years ago, he was learning about finger picking from one of his idols at the time and was told not to "marry" his fingerpicks. Alas, Ken did and he regrets it now.

I think it is absurd to stick with one method/style/device/sound/etc. Try 'em all and try to develop them all to some degree.
