I hold my Commercial Diving Certs as well as a Padi OW. I want to become a DM then an Instructor. My local Dive Shop that I take TDI (Technical Diving International) classes through teaches STI (Scuba Diving Internations) and not Padi. Should I stay with PADI or go with STI. Opions about both Organizations would be great.
