Personally, I am pretty sick of Azetc but Dust and Dust2, much like the old cs_militia, are classics and I just can't get enough of them. I do really like compound but I noticed it does kill the server.
Throwing some new maps in there sounds nice... I mean, I've found a couple really awesome looking maps at

but some people won't stand to wait 2-5 minutes for a new map to download before they can play.
How about a Dust/Dust2 24/7 server with a bunch of other map vote possibilities? The 24/7 map doesn't have to be dust, that's an example (a very good one, I might add)... but I think this scheme is the best way to go, lest we've forgotten what made the original Counter-Strike server so popular.
