Double Transplant for CF?

I just received my packet for my transplant testing and was reading through the material. I will be going to Cleveland Clinic. While my lung functions are still in the mid 40's I'm curious as to what I've been reading. I know I won't be listed as a critical person (my doctors wanted me to get on the list so I'm there in case I get really sick and they start to fall again). In the packet it said CF patients usually get a double transplant. I was just curious if this was the case for everyone or have any of you only gotten a single transplant. I would think it would vary per patient, but it sounds like at Cleveland Clinic that this is a standard. Wondering what your experiences have been?
