I think it just depends on how you look at it. Some groups are smaller with wonderful girls. Some are huge with not so wonderful girls. Some are weak with bad girls. Some are huge with good girls. There was one group in particular on my campus where their nationals did them wrong. Several years later at another school the same groups nationals did them wrong again! I think as long as the members of a certain chapter are happy that is what matters most!
A friend of mine said there was a chapter on her campus that got all the models but couldn't retain them b/c the girls weren't happy! So who knows!
