Finding a brush kit that I felt sounded good and authentically 'brushy' enough for me when used with non-jazz MIDI beats has been a long standing quest for me.  I am also an EZDrummer user and Toontrack recently offered the Nashville EZX expansion for something like $39 so I bought it.   The brush kit in this set sounds the best to me by far no matter what the beat I have applied to it.  It sounds like brushes on the snare and it sounds like brushes on the cymbals.
Normally, I have preferred the sound of the AD drums, but preferred the beats available from EZ Drummer, at least for the music I do.  The ability to shape the sound of the AD drums is nice, and the ability to modify the beats in EZDrummer 2 provides the best of both. However, this Nashville kit has changed that formula for the brush kit.

I just picked up the Music City SDX for SD2 that the Nashville EZX was derived from. I noticed the brush samples, but hadn't tried any yet. Now, I'll definitely have to spend some time with it.
 
Also, I'd be interested to know how you manage the remapping (drum maps) when working between EXD2 and AD2.

I've done this for Superior Drummer and Addictive Drums, it's really handy for alternating patterns programmed for their specific hosts.

Open a drum map meant for EZD, and the AD PDF that shows where each note is received.
In the EZD map, change the out notes to match what the AD PDF says it takes the information on, for each piece of the kit. Save it as a new drum map.
When I'm using their preprogrammed beats, I'll have 2 MIDI tracks feeding AD: one for AD programming, and one for SD programming that rerouted the information to the AD plan.
Probably takes 10-15 minutes...

Thanks!

This is exactly what I did, although it took me a bit longer than Slugbaby.  At least you only have to do it once per kit exchange.
