Random notes:
I find that armor on your head may actually be the most expendable place if you need to shave off a few. It almost never gets hit unless you decide to bathe in an LRM volley.
My builds include keeping the front and back of your Commando equal in armor, and besides the 2D, will allow you to run with full armor. The way I see it, they'll be seeing your back just as much as your front.
Personally, 2D > 3A >> 1B; I don't think either of the other two are even worth your time. 4 ML or even MPL won't cut it, and the other one has very weak missile hard points.
Unless you have an ECM or are running with someone you know will have an ECM and are willing to shadow that person, my mentality is that SRMs will be more useful, albeit they will be much more difficult to use.

The SRM6 comes out in spurts of 2's, so it can be very difficult while chasing down a mech, but on the other hand, you can almost at least get one set to hit because it will kind of track your target for you. Great at taking out heavier Mechs, horrible when it comes to fighting anything with Streaks.

Best thing about this, is that it the missiles come out in one splat, so you can do some serious damage if you get into good position. Further, SRM6 in the torso over the arm in case that gets blown off. Or, you can drop a ton of SRM ammo and updrade the SRM2 to an SRM4 for fun time. If you can get a good salvo off against another light, you'll be on easy street.
2D Build

Fairly standard. You sacrifice a max engine for an ML and another ton of SSRM ammo. Alternatively, you can get the max engine, remove a ton of SSRM ammo, and swap an SL. Easiest, and most effective Commando.
