I just did what you are thinking. I've been at the fixed-wing thing for quite some time though, and have plenty of experience(bush and IFR) with which to market myself. So far, the response has been good, but the proof will come in the spring.
I feel that RW has far more potential than does FW at the moment and it's a million times easier to get people to talk with you as a low-timer. That said, I see the fresh RW grads having an extremely hard time trying to get work. I had much counsel before deciding to make the switch and given my FW time have found most of it to be accurate. I also feel that as a dyed in the wool bush pilot, RW is far more suited to my style and the smaller the town or villiage, the happier my wife and I will be. If you're looking for Van., Calgary or T.O., stick with FW as far as I can tell. I may be wrong, but it seems most of the good city RW jobs go to the guys with heaps of time.
I you want any specific questions answered I'd be happy to share my experiences so far if you want to PM me. As I said, spring-time will tell all! (It better, because UI's going to end...)
