i'd go for no scripts if i was you, they're usually aimed at noobs, but instead overwhelm them with new option menus. If you don't like how mirc looks, just change the background to black and other colours appropriately :)
crossfire was shitty tbh, it had a little nuke button, but that was really all it could do, Undertow was fooking class, subtransit was good and stalkyard was average
