Mid grade and Ultraedge are the same durability and flex a little to absorb impact. UE = Ultraedge.
The only dif is the looks, when off the UE blade looks white, when on it brings the color all the way to edge of the blade.
My wife LOVEs the UE blades, so I suggest that for her. For the Adegan Silver since the LED is white get it with the UE.
Heavy grades are HEAVY and HURT when hit with.
For Bane's Heart,
For her saber choose one of the "Premium Colors" i.e. Arctic Blue, Violet Amethyst.
When you're checking out, in the "Order Comments" section.
Ask politely for the "Premium Color" you chose to be changed to the "Bane's Heart.
That should do it buddy.
