Man, I freakin love Snowbound. It's probably my favorite Halo map ever. Which isn't saying much because I hated Halo 2, but uh.. still! There's just so much about it, the first time I saw the Banshee explode while flying over a tower while I was inside of it I totally marked out.
I'm not sure how I feel about the lag. Aside from one or two noticeable hiccups, it's been great. The only thing else to complain about is when you go to melee someone the same time they melee you, I'm still not sure what determines who wins and it feels kinda laggy. Oh, same for the laser firing as you die. I'm sure that's a balance issue but it's happened to me so many times it's annoying. You get the blast off but the game pretends it never happened.
