I do not have an LE but just got my Maul FX LED convert in the mail today and all I can say holy *****. This saber is unreal. I have almost all of the MR FXs and thought I had seen it all. This is not the case. The weight alone sets this apart. It blew me away so even though I do not have an LE I would suggest dumping it if you have an FX on the way. The only thing I have to compare it to is the Hasbro and the Pepsi saber. The FX is in the middle. The detail is very impressive. I will be changing the socket head screws that hold the conversion.
I don't have a MR Maul LE, either. I do have a Oz Mau saber, though. I'd say thats pretty comparable. Here's my shot of it next to a MR Force F/X Maul.
