Pigeon Conditioner in Winter

After Natureboy got me a bag of conditioner in the spring i have been hammering venues with it all summer but now with the cold months upon us has anybody used it in the winter and is it as effective as the warmer months?

I havent personaly used it in the winter but I have been told it is not as effective due to the fish being less active, so they are not routing around for the small particles like they would in the warmer months.

You make a good point. Might just stick to the boilies approach then as its less energy used to get maximum protien and other goodness.
