I am finding that I keep going back to the Avatar kit, but you NEED to get the Latin Percussion and I would recommend the Clausterphobic kit too, I like the chimes in that one better than the Latin Percussion. The Hit Factory has great kick drums. Music City is ok, not as good as I had hoped. To start out I would go with Latin and Clausterphobic. When Tom Roady introduced me to SD2, he recommended that I get the Jazz, Latin Percussion, Nashville, and Funk Masters add ons. I did that and they all were great. There are two types of add ons with SD2. There are the EZX expansions which work with EZDrummer and SD2. There aren't as many articulations with those add ons and you will notice that their kit sizes when loaded in are smaller than the SDX kits. The SDX kits are SD2 kits, more articulations which make the kit sizes much bigger, that is why I upgraded to 8GB of RAM on my MacBook. I can help you with running your system on the Mac if you get one, Dr. Shark is using a PC laptop so he would be the man to talk to if you use a PC.
