I would personally recommend going for the small, friendly and informal but commited flying club for the FIC. Larger more commercially orientated schools tend to have a conveyor belt mentality and IMHO the FIC requires a different approach than most other flying courses.
FIC's are more about personality and learning how people respond in certain circumstances as much as anything technical so you need to be somewhere you feel comfortable and strutting around in the gold braids and raybans amongst hoardes of budding teenage airline pilots at one of the larger FTO's would completely spoil the ambience of a good FIC!
Find a nice little club, a jolly FIC instructor and enjoy the course.
VFE.
