i chose my fascinating topic first.. applied to a very good uni... offered place after interview... met second sup... first one was away at the time. i start in a few weeks. i dont know what my 2 sups are like. i did like the 2nd sup i met at the interview. i hope it all works but in my case i accepted sups i was offered and i dont know any of them. the uni however has a very good reputation for research - one of top 6 in UK :-)
