I find that lighter jackets make it easier to use layers instead of trying to make one or two heavy layers work instead. I would rather wear an insulated long sleeve under shirt, a thin over shirt, a fleece jacket, and then a breathable jacket over the top of it when I will be moving around in cold weather.
On the other hand, if I'm going to be stationary for long periods of time I'd replace the thin breathable jacket with a heavy layer to all of the rest of the above along with with heavy gloves or mitts, and an insulated hat.
En-route to a game stand or blind I'll be carrying the extra gear, once I get there I'll swap out the light jacket for the heavy one. Buy both? Maybe not, you can probably work out a system of layers that allows you to bulk up when sitting still and dress down when you are on the move. I guess I'm asking you which problem you are trying to solve; it's very likely I don't fully understand the question.
I can explain it to you but I can't understand it for you.
