Yes. I do reward my CSAs same as I do to my PSAs. For me there is no discrimination between a CSA and a PSA. I got many active CSAs from the Price-bender's auction who did all the things my PSA do to me. They shared their problems, asked for help. They communicated with me regularly and followed what all I said. At that time I decided to do the same with them as I did with my PSAs.
It is very much helpful, atleast in the sense of leadership and business even.
