Here's my setup in SW TN…
Early season (60+ degrees) - wick baselayers from FL and a pair of thin pants. They're all about the same IMO wether it's FL/Kuiu/Sitka
Mid/Late season (30-60 degrees) - wick baselayers, mid weight or furnace merino baselayers, and my guide jacket & pants from Kuiu. I'll throw a Klamath hoodie from FL and my drake vest if need be also. Layers depend on temp swings. Guide jacket&pants will keep you dry in a light rain or mist too.
Anything below 30 w/wind - baselayers, guide jacket&pants, then throw on my drake hydro-hush bibs& jacket when I get into the tree.
Gotta be cold and windy for me to throw on the jacket because I don't like being restricted when drawing my bow.
I had some FL pants but hated them bc they were short, I'm 6'3" 205lb so I went with Kuiu. The fit is great, stretchy for drawing a bow too which I like. The deal is that everyone has an opinion and you can certainly go mix and match as long as you later appropriately.
I don't ever post but enjoy reading all the threads just figured I would chime in here since I was in the same boat a few years back with moving from my 20yr old scentblocker suit.
