Irish,
Greetings. My personal choice related to Ferguson Modern vs Ancient, and for what was for me also a considerable financial outlay, was one I pondered for some time. I already had a ‘casual’ kilt in modern and when considering and investment in a quality kilt, the modern just struck me as to dark (color wise). If just felt the Ancient color scheme just stood out more effectively and ‘represented’ Ferguson a bit more boldly (my humble opinion).
Hope this helps.
