I agree with all of the above.
Sensei were only added to the list of people able to header worthy content recently. It was decided that, as the more artistically experienced and accomplished staffers, they are of course in a perfect position to judge what should be headered.
On the balance issue...I completely agree with Guerrilla. If we were to header every good BSG model being made out there, for example, we'd see little else on the headers and for every person wishing their was more BSG content on there, we'd get 5 bitching that there was too much...
