I have the same trouble and it's something I want to delve into. Is your site fully indexed by bing? Mine is about 1/4 indexed now but I haven't seen any significant increase in traffic from bing, as I come up pages deep in the SERP most of the time and my pages are newly indexed. I'm uncertain how fast newly indexed page reach the SERP.
