I have heard that USFS is trying to figure out how to investigate how to get a Senior B competition going in the US, but they are being remarkably ineffective, since they are concentrating on trying to get buy-in from the clubs that run events like Liberty and Lake Placid International Dance Competition. Those clubs run their events as a cash-cow money raiser, where they attempt to get as many entry fees from skaters at all levels as possible. Rumors back from those efforts have unearthed fears by the clubs that the expenses of getting the foreign judges and Tech specialists required (you need 3 countries at least represented) would cut into their take for the event too much. Also they fear they might not be able to have as many skaters participate as they do now.
Another method for setting up a Senior B needs to be tried-perhaps looking for interest among skaters and teams who will be moving up to Seniors and their coaches from both the US and Canada, or from elite level dancers, both junior & senior, who want to get an international read on the levels of the pattern dance in next year's SD.
