I was a Rho Chi my Junior year. And no, I didn't do it because I wanted to get out of rush, or that I was bad at it. It was quite the contrary. I was a pretty good rusher. And one thing I can say is that I think I was VERY well prepared to deal with situation like those described above. Luckily, I didn't have to face one with my own group, but during our monthly training sessions the semester before recruitment, we were expressly told NOT to promise girls that they wouldn't get cut, or that they would definitely get their 1st choice. Luckily, as long as you ranked every house you went to on pref night you are guaranteed a bid, we only had problems with girls not getting bids who suicided one house. I really think other schools should take a hint from our Rho Chi training procedure. I still see my girls now and then when I am on campus, and still get excited when they stop to say hi
