I recently started playing Battletech with some buddies over Megamek, but I'm still really new to the game, so I was wondering what some of your favorite mechs are. I've played like three games so far, used Warhammer, Rifleman, a shitload of Urbanmechs, and an Assassin (who's sword I couldn't figure out how to use). Most of the time I've just tried to hammer things from far away with PPCs, lasers and ACs, and then DFA with Urbies whenever anything gets close. Probably not the best use of them, but its pretty hilarious.
What sort of mechs do you like to use, and what sort of play styles do they play to?

Also, third fucking time trying to post this, lol SQL_FAIL
