How many of your BCI are on Rabbits?

How many of you guys have your BCI on rabbits?

I've been considering getting one for a few months now, I wanted to get something a little bit larger the 6 ft, but don't want to get into the 15ft range. From what I've read 10 ft is pretty common for a regular red tail which is right around the size I'm looking for. Only thing I'm concerned about is prey size. When they get to that size do they need to be on rabbits or are Jumbo rats still a good prey size? I don't have an abundant avilablity of rabbits, and I also not into having to kill them myself. So I was wondering, how many people actually have their BCI on rabbits and if rats are a suitable prey size for the entire life span of a BCI?
