On a related note, if anyone is putting together a touring setup (or just needs new bindings), I have an extra pair of Marker Tour F12 EPFs, brand new in box that I do not need - I unfortunately had a tech accidentally drill for the non-EPF version so I had a set of those mounted instead.
For those who aren't gear hounds, these probably the best frame style option for the vast majority of people (because even if you think you're the gnarliest dude alive and weight 220 lbs you almost certainly don't need a DIN above 11), as they're one of the lightest frame bindings out there at 1107g per binding - compared to the Duke's 1432g and Guardian 13's 1470g.
They're size Large, so would fit a boot sole length between 305mm-365mm and have wide brakes. I'd be firm at $300 (otherwise I'll probably find a use for them down the road).
