Hehe - touché, Les. Indeed, down strokes ("brush" strokes) are no longer possible to me since I use picks. But I only needed that for 'Bad Bad Leroy Brown' and so I can live without it, but of course that needn't apply to other people playing different styles or even instruments.
I also don't want to hide another disadvantage of picks. Once you don't damp the string any more before you touch it with that hard instrument you want to pick it with you might experience some short buzz ('steel on steel'?) which might be interesting - sometimes. But I admit that it also bugs me at some occasions.
So I keep the nails on my right hand long, first because I'm used to the feeling (I would feel kind of amputated without this, believe me) second because there might be a situation where I MUST do 'Bad Bad Leroy Brown' (ahahaha). Effect: I can't use them for playing any more because they are always TOO long.
Every way to do something is wrong. Fortunately there are ways not quite as wrong as others.
Keep on learning.
Q: Why do (insert nationality of your choice) put viagra to the compost?
A: They believe that with this the can use worms as nails. (Hello, worm nails.)
