I went back to the drawing board starting off with the basics of EL Nino and its developing via references from NOAA, research papers, etc. When dealing with EL Nino structure, it's a completely different process then La Nina. With EL Nino you're either going to have EP (canonical) EL Nino (or EP to say central based) or your modoki (warming in the central or western ENSO regions.
