How do you determine which .M2 to use?

[Nitric]

So after playing around with Glitchy's for a while and trying to edit some weapons, I ran into a problem. I'm trying to edit a Heroic Bloodvenom Blade into the MH warglaive. However, when I try to locate the weapon in Glitchy's, there are four 1h sword Icecrown models. Which do I use? Is there an easier way to do this?

Download wowmodelviewer > import MPQs (but when you install, it automatically detects where your MPQ resides I think) > choose a character > equip that character with the weapon you want > click on view > click on model control > and there you see which M2 are being used.
