With some practice, a pick will give a real nice, consistant level.
(Especially nice for recording)
You might want to try resting the fat part of your hand
(under the little finger)
on the bridge to provide a constant point where the pick meets the strings.
This keeps the "point of attack" from moving around while your playing
(closer to the bridge p/up or closer to the neck p/up)
which will cause your tone to vary.
This also makes it easy to add a little palm mute too
by rolling your hand up onto the strings just a bit.
...works great for pounding eighth note lines.
You might also want to try a medium soft (bendable) nylon.
I found that takes out most of the "click" you'll get from a heavier (guitar) pick
and the "scrape" you'll get if you're using roundwounds.
I hope this helps!
PS- Please, let's not have this thread degenerate into another fingers vs pick debate...
