+1 1984 is a key year for the WS. Anything prior to that is really bottom of the barrel. How is the FG market in your area? Would probably be a good choice for FG.
The Ross sounds better, but the Ross name is tarnished by all the dept store junk Ross made as well. So unfortunately, it can be hard to convince the average buyer that it is a good bike. Depending on $$, upgrading to 6 speed DT would make it a nice bike. Some Ross's used BMX sized stem, so check on that. Not worth a 9 speed upgrade IMHO.
