TwoTikkas, just a heads up, I have used the Sitka Timberline jacket and the Kryptek Aegis Extreme and they are absolutely nothing alike.
The Timberline is more or less just a windproof shell with very minimal insulation in some parts of the jacket, definitely built as an active mountain hunting jacket.
The Aegis Extreme is 100% the opposite end of the spectrum as far as the two jackets go.  It is big, heavy, bulky, and doesn't pack well.  It is waterproof (at least in my experience) and windproof.  If you're mountain hunting and you walk more than 2-300 yards in it at a normal walking pace with any kind of elevation gain, you will be dying to take it off.  It is, however, perfect for late seasons sits, horseback rides, and a layer to throw on first thing when you get out of your sleeping bag.  I used mine late season for the purposes I just described and I was pretty happy with it.  My only complaint was that I wish had went up a size (from L to XL) because if you wear much more than a base layer it is kind of snug around the shoulders I thought.  Even with just a hoodie its a little tight for me.
Just thought I would let you know because you mentioned you wanted a jacket "a little warmer" than your timberline.  It is a LOT warmer.  If you're doing lots of not moving in cold temps, it'll be perfect.  If you're wanting a jacket that's just a little warmer and still want it for hiking around in the mountains, I'd check out some other options.
