I have a pair of 4FRNT STL's in a 183. These were ridin for this whole season and took a hefty beating before they lost maybe an inch of edge underfoot.
These skis are in pretty decent shape, no coreshots and still have a good coat of wax on them. They were mounted once at centre with marker jesters.
I dunno what i can get for these but offer up.
the nickle is for the size reference of the edge missing:
