What are the best lightsaber replicas for dueling?

Hello everyone, Feelicks here. I've been planning to get some good replica lightsabers for dueling, in need for a duel I'm performing with my friend outside the theater on the night of the Episode VII premiere. I've been taking a very good look at Hasbro's Force FX Signature series, and Ultrasabers, along with Master Replicas, and I'm considering the Force FX series or Ultrasabers, which one is the best in your opinion?

 

force FX lightsabers are rather heavy-ish,

so if you want to duel with them and clash them around with another saber be careful,

they are also not the sort that you can wave around in tight spaces

 

Ultrasabers heavy duty blades, not even a contest.

 

What kind of dueling?
Film?
or
Martial Arts practice?

 

Master Replicas are more for display purposes, certianly not fit for dueling.

Master FX, as someone else stated, are quite heavy after a while.

Ultrasaber seems to be the way to go.

 

Ultrasabers, hands down.

DON'T DUEL WITH MASTER REPLICAS!
It kills the leds inside the blade.

 

And MR scratch VERY easily.

 

I'm looking to start a collection, I don't want to be duelling with them. Purely for display, I'm reading the master replica series?

 

Yeah, I think so. Just be aware that the MR sabre hilts are actually ever so slightly larger than real life scale so they could cram the electrics inside. But I'm not aware that there are many people who are that anal about scale.
