Somewhere, someone talked about the element X. But searching from the phone is tedious. Thinking about it more, I believe their four mids are two tops and two bottoms.
Notch top & bead - warrior
Notch top & beadless - scout
Angle top & bead - karma
Angle top & beadless - element
Good chance I'm way off too. Maybe Allen or JCass can clear it up.
Mmmm I loved the Element-X. The Karma just didn't feel the same.
