To put on two 1 handers, you have to specify which slot they go into, but with the 2h weapon, you only need to tell it to equip. If you try to tell it to equip it to slot 16, it'll tell you that it can't.
/equip 2HWeapon
/cast Raptor Strike
/cast Wing Clip
/equipslot 16 NameOfMainHand
/equipslot 17 NameOfOffHand
But I think you're putting too much effort into it. You should either stick with doing the raptor strike with the 1 hander, or find a 2H weapon that has better stats than the 2 1h weapons.
Oh, and if anyone sees a rate down on a post that says to do "/cast wing clip" first, assume it's from me. You guys HAVE to pay attention to what you're doing. Raptor Strike hits on Your next attack, while Wing Clip is instant and counts as a hit. If you have a slow 2h weapon, you could be sitting there for 2 or more seconds for Raptor Strike to go off.
And another tip for this macro to work right, Go into your Interface options, and turn off the Auto Shot/Auto Attack option. This will prevent you from automatically swinging your melee weapon when you get into range, and messing up your chance for a quick hit.
