Hi, I think folks were confused by what you were asking, but I get you..
I have the Reason Drums Refill v1 because I still have reason 2.5 and it is very good. I picked it up after v2 came out so I got it for a bargain price too.
There are 2 identical refills on the disc 16bit and 24bit. The 16bit is better if you don't have much RAM but does have artefacts on the tails of drum and cymbal hits. 24bit sounds the best but can use a ton of PC RAM and CPU power if you're using an older machine (for what it's worth I have a 3.2ghz P4 and 2gb RAM and 24bit runs fine with Reason also slaved to Cubase SX3)
There are several pre-made kits for different styles of music in different formats NNXT and Redrum. NNXT is the one to use for maximum flexibility and it is possible to edit and create kits e.g. drum brands/sizes, if there are direct, overhead or ambient mics (for each drum) and if there is, control the levels. It takes some time to put a "custom" kit together but worth it.
Definitely a thumbs up from me.
