Some of these are kind of neat. Tron's is a semi-slaughter map that's a tad crude looking but fun to play. Headthump's has some interesting brushwork (albeit some horribly stretched textures and some gaps in the geometry), but is starved on ammo (had to axe a hellknight to death, etc.). Zwiffle and RPG's maps are the cleanest built maps. Zwiffle employs some annoying spawn-behind-your-back moves, so be aware. RPG's kind of resembles a coagula style map and is the most "fair" but is a bit repetitive. Of course, most of these niggles are understandable with a speedmap pack. RPG's and Tron's are my suggestions.
