Sorry it took a while to reply. It has been back to work for me, so my replies will be limited.
As for the TTSS, it proves that the classic example of irreducible complexity is reducible. The ID crowd placed the flagella as a test cast for their hypothesis. The test case failed as predicted by the Theory of Evolution.
Claiming that the flagella could "devolve" is not a valid argument. Assuming the flagella did devolve, then the argument of irreducible complexity still breaks. It is reducible. Therefore the test case for ID fails again,
