The new blackbird Mamba on the new warbonnet website looks very tempting. Im thinking I should take advantage of the sale on the winter quilt- but am not sure if I will be too warm in a zero degree rating? I typically get real warm when sleeping (Im my wife's down blanket!) -Does that make me a warm or cold sleeper? never figured that one yet... Any advice before I jump in? I do plan to buy a lighter TQ for warmer months anyways, but for winter...
