Love finding these old thread.
If I were to choose from the chapters that were present at CSULB in 1981, I'd go with Alpha Phi which was the other house that I'd preferenced. Their songs were so pretty and I really liked the sister that was there for me at the preference party.
From the other NPC groups I'd choose the following:
Kappa Kappa Gamma, Kappa Alpha Theta and Pi Beta Phi because I have family members in all of those organizations and I admire their philanthropies. Plus I favor badges that are symbols (arrow, key, anchor, kite).
