Its one of the "finer points". Greg Williams never really gave a hoot about the comb. He considered it a small deduction. I personally want my birds combs right. Its just something you have to work toward. One of the last things you would cull for providing it is a PEA comb. My Buffs have excellent combs while my lights, especially the males, could use some improvement. Type is paramount followd VERY closely by color and feather quality(width of feather). I would not worry too much about the comb until the other qualities are pretty well set. Again,most of this is my opinion...others may well disagree.
