I have all of the ADpaks. I mostly use them with Addictive Trigger for kick, snare and tom replacement. I like the work flow in EZ Drummer for building drum tracks. I sometimes use AD2 after I've created drum tracks with EZ Drummer. If I wasn't so heavily invested in AD2 and not using the samples for drum replacement I would take the King's advice and go EZ Drummer and/or Superior Drummer. I don't know if it's still available but XLN had a download page for gm versions of the AD Paks.
