WTT 179 Obsethed for 169

Sick ski but i am clearly not big enough to be whipping these around in tight east coast trees where I spend most of my time. I was hoping I could swap these out, they have only been used a handful of times, bases and edges are pristine. Topsheets have a few scratches. They have already been drilled twice, most recently for a pair of small barons on the line. Im not sure what the first mount was. If anyone is interested Ill throw up some pics.
