It would still be a Mack Snow. Spotting like that happens a lot with het Blizzard macks. I am by no means saying thats what it is but I have personally noticed any het blizzard macks I have produced all tend to have heavy spotting.
Thanks, good answers! i know it is generaly an ms, just didnt know if it was like a jungle variation or what. the broken tail pattern vs classic bands isnt common for ms is it? it seems out of place to me. the blizzard scenario seemd poss. too with so much spotting....
