The nuke is pretty darn good but i think the double turrets with rocket pods is the best setup i have tried, they just smash everything. I am not running shields on them, i tried what chrislognshot suggested, and it does help with seeing enemies in certain areas, but the shield on them does come in handy when yours becomes depleted. I am debating on switching them back on.
Almost hit 50 on my Commando last night but was falling asleep while playing so i decided to call it a night and just finish it tonight, i think i am only a few thousand points away. Thanks to Hollowhound for helping me level up a bunch lately.
