Here is a nice version of the Dark Arbiter I found. Keep in mind this is only possible with a stunt version and QD installed. I made a jumper for the led QD so I could put the led in the opposite end of the hilt. I really like this version and will probably keep the saber like this. It's very comfortable to weild. It's short . And it looks Amazing!
It has a DVA MLS. It's kind of similar to Obi-Wans 3rd lightsaber. I actually had a closer version by using just the switch section of my Reaper with the grenade grip ,pommel,emitter if the Dark Arbitor. I loved the way it looked however there was not enough room in the grenade grip for the Batt pack jumper cable and a MLS unit.
Here's the Reverse Arbiter
