XT disc rotor swap

[Splatter Paint]

All, I've just bought a pair of wheels with two splined xt discs, one an RT77 the other a RT78. Does anybody want to swap discs so I have a matched pair? The 77 is new the 78 has been fitted and has light scuffs where the pads have rubbed but is otherwise unworn.

Anybody else got a mismatched pair?
