I agree that we need a short rotation with maybe a random fun map in the middle, kind of like what Yahoo was saying. My only suggestion is that we need to be careful which maps we put back to back. No custom maps should ever be put back to back, and custom and not so popular regular maps should be followed by a very popular map (ie not italy).
I have my own personal likes and dislikes of particular maps, but I will make no comment since other people seem to like them.
In the *random* fun map spot I would rotate probably (@ 10 minutes each) deagle5, sk3, tides, aztec?, chateau, etc.
I know I am forgetting some good ones…
