I believe that Pi Kappa Phi at TTU is a great group of guys that is often over shadowed on campus. The level of respect I see out of the guys wearing their letters is much higher than other Greek chapters on campus. There doesn't seem to be a a lot of them though, and their activities seem to be limited to 1 or so that I hear about. If they get a bit bigger, get a house, and do something positive to get known will help them become a top tier chapter.
P.S. This is not PIKE (Pi Kappa Alpha)
