If you like open tunings, try looking for more of a jumbo size - so the outline of a GC but with the depth of a dread. That'll still give you the "boom", but with more precision on the midrange.

My problem with dreads for fingerpicking is that generally they don't have the precision of a waisted instrument, so with strings ringing on you can't hear the individual notes clearly. Not a problem with flatpicking or strumming, but not ideal for fingerpicking. Of course, as much of that depends on your style of fingerpicking - if your style is that kind of crisp ragtime bounce, then a dread might suit you. But it probably isn't going to work if you use a more classical-style approach.
