Mauler of course, always the Mauler!
Teee he he. Just kidding. That crazy big ol' Mauler, eh? :D
I have always favoured the "big UAC backed up by plinking" found in some designs. As a predominantly clanner guy, this means things like the Stormcrow B (UAC/20 and 6xERML) or Night Gyr A (UAC/20, 2xStreak-6, 2xMPL and an LPL just for fun).
Not a huge fan of the smaller /2 and /5 ACs. But as a Falcon those are all over our standard designs, so I guess the Summoner Prime, Kit Fox Prime, Night Gyr Prime, Turkina Prime, Jupiter, etc counts to some extent (unfortunately!)...
