I wouldn't worry about it. BG will taper off feeding when the water gets cool enough.
Completely agree. HSB will shut off after the BG, when temps get into the 40s; trout will feed all winter but will slow down a lot when water gets into the low 30s, at least as far as taking floating food goes. I've wondered if using sinking pellets would be more effective when the water gets coldest; there certainly seems to be a lot less surface activity then. I don't see any HSB activity at all once temps are down into the low 40's or 30s during the depths of winter, but feeding activity seems to pick up in the spring as much in response to longer daylight periods as much as water temp, at least at first..
