Oddly, I never posted here.
I like to have a heavy weapon for my primary, usually the 2700, though if I ever get it working, my 1200/12K would also work. For back-up, I like to have a backpack with a smaller blaster like a MD 4000 or an Equalizer, or maybe even both if I'm running the 1200. I also carry a couple of water bottles for extra ammo.
But in our wars, I usually just carry one blaster, since the battles are so small and short. For these, the 1200 is my preferred blaster by far, since I like to have mobility, especially if I'm not going to wear my backpack anyway. I'd like to get some camoed cargo pants, so I could carry a real small blaster like a MD 3000 or XP 220 in the event that we end up playing OHS or CTF, which generally require more water than OHK.
I've never dual wielded though, and I really think it's more of a hinderance than a benefit, unless I'm on base defense, and need heavy firepower and a lot of water, and don't have my 2700, in which case I would probably use the 1200 and Vanquisher.
