Are they essentially the same dimensions? If you were to put them side by side and they'd be exactly the same except the emitter opening? Can someone post some comparison pics?
The FX is fatter, less of a taper at the emitter cone. If they're side by side it's pretty apparent. Sorry, I don't have pics. I think it's the best looking of the FX sabers though, and if you sneak it in among LEs it won't stand out like a sore thumb or anything. I had a BD Maul LE and it looked kinda iffy to me, so the FX doesn't suffer much, comparison-wise.
