131-100-119 189 RAMP Groundhogs. Mounted once for FKS clamps. Guy told me for a 28.5 boot but I was unable to get mine in without a 328 BSL. Sounds like your 315 would be a perfect fit. Very very light use - guy said < 5 days and the skis agree with it.
131-100-119, rocker in the tip, stiff camber under foot, and stiff flat tail, 19.5m radius. Looks to be exactly what you are looking for.
$225 shipped sound fair? Find some cheap FKS clamps locally and you are golden.
