Currently, BASTARD #6109 is classified as a Peak Spike hair. However, it appears to have both Peak Spike and Top Hat traits, which combines to make the Peak Top trait. The tophat trait is clearly defined by the right half of the hat. No other head traits have pixels in that area.

This is #6109 above. Below I will list other bastards with the peak top trait for reference.

Should Bastard #6109 be reclassified as a Peak Top head trait?
