The way to beat STSF is to hit them hard and fast. In that respect, congratulations.

However, the decently skilled people will fight with preps. Throw in stone skin/protection/aura/shield, or at least two of that list, in the equation, and you would not have as much success.

I'm sure you have many examples to provide beating STSF. The general consensus is that STSF gives too much of an edge to any respective character, and that has been proven countless times.
