I think the consensus on CMOS sensors is to not use bias at all but to use only darks and dark-flats. You can actually use biases if you lengthen the sub times a little as a lot of the issues people have are with combinations of certain gains and short subs. Dark flats are long enough to avoid the issue and you, in effect, get to take out the bias signal that way.
