I have the mace windu MR FX saber too that was the first one I got and am very happy with it. It's going to be hard to resist the urge to duel with them but I will be keeping them for display purposes only. I plan to get a vader one for red and obiwan for blue and possibly Luke green version as well.
I am sure you are aware but due to their design the Jedi Luke and Obi Wan ROTS are not very accurate. The Luke ANH Blue is awesome. I had it next to my L.E. Master Replicas Luke ANH and could not tell the difference. The ESB Luke is just as good I assume.
Just FYI since you got green with Yoda a nice ANH Luke might be good for Blue.
