If you know Kong Sang Koon, do you really need to know O Sip Sa Bo?
It would seem like Kong Sang Koon fits the curriculum of TSD better. You can see bits of Pyung Ahn, Bassai, and Chinto in it. O Sip Sa Bo has some elements of Naihanchi in it, but it seems to fit better with a different grouping of hyung.
