I look at it this way, There are those that ride Harley's and those that ride sport bikes. Same thing just a different culture. There are several x-airline types with my company, and as a whole they do a good job. It takes a while to get them to understand that it's work. Load the bags, get the coffee, file a plan ect. I have seen a few of these guys "wash out" because the 91/135 environment didn't suit their tastes and felt that it was beneath them. Most of my clients in the 91 world don't want to spend the money on an x-airline guy because there is always the fear they will get called back.
Just my thoughts on this.
