Hello Kilt'n'Khuk, welcome to the forum.

I think both 4 and 8 yard have a place.
I wouldn't think of wearing an 8 yard down the beach on a hot day, my 4 yard Bear is great for summer, but take me up in the mountains where it's cooler and I would feel naked in it (not to mention exposed). Up there and anywhere on a cool day I feel both comfortable and warm in my Cheapkilts 8 yard blend or 8 yard worsted wool.

on a very cold day, I could not have been more comfortable, it was heaven on earth
