Forum:New Vegas: Gunslinger vs. Commando

Okay, I'm working on a combat build that specializes in Guns, Speech, Lockpicking, Science, Repair, and Sneak (may go with Energy Weapons or Melee as a secondary) and I am trying to decide between the Gunslinger and Commando perks. I can choose both, but if I'm able to narrow it down to one it'll open up a slot for another cool perk not currently in my build, such as Silent Running, Concentrated Fire, Strong Back, Rapid Reload, Toughness, or Robotics Expert. Any thoughts? Also curious which of those perks people think are most useful.

On a related note, I have yet to decide between Energy Weapons and Melee - if I go with Energy I plan on taking the Laser Commander and Meltdown perks, as opposed to Ninja and Unstoppable Force if I choose Melee. I suppose I could also focus solely on Guns and select two additional perks from the above list.

Any insight would be greatly appreciated! I can provide the perks forecast if necessary.
