Shanerbanner10: That combo would be awesome.
Just be aware of all the different SL, LT, AR, SV acronyms. SL= Super Light, LT= Light, AR=All-Round, SV=Severe. Generally they're all pretty similar but the face fabric towards the SV end tend to be more tough and durable. Not sure what type of work you're doing, but it might make a difference if you expect you'll be bushwacking through branches/limbs, brushing up against sharp metal, etc.
Also the main differences between the Alpha, Beta, and Theta jackets are the cut. Alpha is a pretty average cut for general purpose use. The Beta line is a little shorter in torso length for extra mobility, especially if you're wearing a harness or whatever. The Theta line has a much longer torso that comes well below your waist for the maximum amount of coverage. The fit of these jackets tend to be for average to athletic build, and they are plenty long in the sleeves which I'm very thankful for being 6'4".
I have the Atom LT Hoody and have worn it heavily for the last three winters, and it's still going strong. Whenever it comes time get a new one I'll get the one without a hood, because I rarely use it, and it's not adding extra bulk when I wear it for everyday use.
