What?!?! Where did you see the prototype(s)?
I would imagine that the blade of the 720 will be quite different, as will the AL handles. I thought Mr. Ellishewitz said the handles would be multi-colored G-10. That by itself would make them different enough for me.
Pray tell, where did you see the prototype(s) and, more importantly, are there pics on the 'net?
