I've seen both of these thrown. Unfortunately, they had different drillings. Yes, you can get both of them to look pretty similar. In my opinion though, the TS&A is earlier, and stronger, more continuous at the pindeck.
Something I hadn't really thought about, but was mentioned by another BR user....the S&A is real smooth, with deceptive hitting power on the backend. The guy I saw throwing the TS&A was a cranker. Ball drilled 4x7??. No X-hole. It just came off his hand strong and finished strong. He had the pin and MB stacked to right of ring, and thumb.
I think the greatest thing about the Vanguard core and the Morpheous cores are that you can drill them to be monsters......or smooth-purring pussycats...with CLAWS!!!
