I mostly use the Swing type Realdrums - if they are the same kit.. I think out of the box, the cymbals and hi-hat sound a little bright and need to EQ down a bit. The snare is fine, but the dynamics may need some compression, I too use it for sketching and demos.
I've yet to try this, as I don't have Melodyne yet - I've heard you can use Melodyne it to extract drums part to midi and use a replacement library sound (BFD etc..) - that would be a great option if possible.
