are those side sprigs? if so, I am afraid you should not breed him. side sprigs would ruin the whole line. can you post more pics of his comb? the more experienced ones will tell you what to do.
I will disagree though that side springs dont "ruin" a line because even some of the best lines carry the recessive genes for side sprigs.. amongst other ugly recessive traits like vulture hocks for example. I know this for a fact.
The batch of eggs I hatched from the same breeder/same line as Redbanks birds I hatched a chick with a side sprig. Do Redbanks's birds look ruined? They most certainly do not, they are stunning. It just so happened that I hit the genetic lottery (not in a good way) and got the worser gene pool from that line. Redbanks was very fortunate and got birds with the better genetics. The origin of the birds from that line were LP and GFF.
Even the most well bred lines from the top breeders are going to throw some not so pretty traits from time to time. Marans are still in their infancy as a breed and havent been refined to the extent some of the older breeds have. You are correct that it is best to cull these traits when you have the luxury to cull. But I will quote Redbanks and her wise words, "dont throw the baby out with the bath water."
