Partly with the Top Houses thing is they don't have to try as hard so they may not work on their conversation skills as much as they might otherwise. Also, when it's a chapter you PERCEIVE as best, their foibles come off as charmingly normal. Whatev. And it points out that every single chapter has gals who are great talkers and others who just aren't. Especially for the first round of rush, the best rushers are those who can just push on and find common ground 4 times per party, 10 parties per day. That's a rare and valuable skill! No matter who you get tomorrow, their top, your top or a whole bunch of in the middlers, tomorrow is a new day so start fresh with a clean slate on which to build your opinions. You may find that that phony baloney chapter really does have some authentic and cool young ladies as well. Or maybe not - only time will tell!
From an RFM perspective, you're making me laugh because if everyone invited you back, you'd play havoc with the return results. One of the statistics the chapters look at is what percentage of girls want them, and some chapters expect all but 100% returns because of their status. Drop that #1 chapter into the #15 slot and they'll be horrified! Which makes me laugh
(but rest assured, only the pencil pushers know those results. You won't be hurting anyone's feelings)
