For those who care to know (I doubt that anyone actually does) but the Scott ST is the same fly rod as the STS. Scott added the second S kinda midstream, so the first rods produced were labeled ST and the later rods were labeled STS. Nevertheless, they are the exact same rod and may be the best tarpon rod out there.
Why all the commotion, well call off the search, we located an STS 9011/3 on eBay and executed. It is currently on the way. So the search for the old Scott ST is over.
