To OP:
As stated, their are tons of loops (thousands) but to for a specific type one may find they need some 3rd party stuff.
No way CW could cater to one or the other and I don't think they do.
Many (or most) of us have 3rd party plugs. I have had kontakt for ages for instance, and I have plenty of Kontakt add ons that I paid for also. Plus Ozone 5, Sound Forge 11, Reverberationx64, etc, the list goes on and on.
So you need to add to your library for your own specific needs, that's the answer to Drone7's "dilemma"
Or the other software's like mentioned above that "do" advertise and cater to loops, etc.
