Went to see Dick Gaughan last night and he too mostly flatpicks (though he finger picked a couple of tunes out of all the ones he did).

I'm the opposite to Beast in that I pretty much fingerpick everything and play with a pick when I need to make more noise. I put it down to me being much shyer than him and much less noisy :)

For me it's what I grew up listening to and playing. Though I used to play blues and rock in a band, most of the things I played were influenced by the people I liked - James Taylor, Dylan a bit, Tom Paxton, Judy Collins, Joan Baez, Leonard Cohen (because all his styles were in my John Pearce Folk music tutor!) etc etc most of which was based on (to my ear) fingerpicked rather than flatpicked tunes.

But I now look at people like Chris Newman and others who I like and wish I was more comfortable with a pick.
