Query: Curved/flat differences

If you want a capo, definitely go with Dunlop. However, do not get the flat capo (this one) if your guitar neck has even a little curve to it--in that case get a curved capo! I know it sounds obvious, but the flat capos do NOT sound good on a guitar with an even slightly curved neck. Makes the strings buzz/rattle.
