Why don't you want beta maps in your Rotation, I don't get it. Some of them are very nice to play....
My proposals: 1day, propaint1, nitefactor, dye32, rome, wwp3fix, freedom, hillside3, island, litt, nolandr, pbcup_2fort5, pbcup_everglade, pbcup_renoir, pbcup_gladiator, pbcup_sanctuary, remenissions, tunnels
Only suggestions, comment what you would find good, these are just my personal favourites.
And yes I kinda like the pbcup maps cause they offer a lot of space and/or different ways.
