Experimenting with new strings for my daughter, love the TWU database and tools, but noticed that the string stiffness for Wilson Sensation Control is lower than that of Wilson Sensation (150 vs 169 lb/in). But the string description says that WSC is stiffer than WS. So I was wondering, whether the data in the TWU database is maybe accidentally swapped? Would make sense that WS is at 150 and WSC at 169, not the other way around, no? Thanks!
