Do whatever you feel is best vod. I do like your colour scheme though! Not that I'm biased toward red mandos or anything though 
The new route is certainly quicker. Managed to finish cutting a shoulder, the gut plate and most of the cod this evening. I also started thinking about a sidearm. In keeping with maintaining a low cost to the build I dug out a £1 revolver I had from Halloween and started cutting:

I removed the hammer (a lot of the SW pistols I looked at didn't have them) and I plan on filling in the detail running along the body side of the barrel (the little line set into the bottom of the barrel) I also plan on filling the cylinder so it doesn't look so much like it's holding bullets.
That scope is a placeholder. The revolver is actually quite large, but the scope (an AK47 toy part) makes it look tiny. I plan on taking the LED in the scope and housing it in the body of the revolver so that it lights up (which will look awesome in the holes on the barrel.
EDIT:
Finished cutting out the plates out from the bin. Still need to go in and trim each plate though. Laid some of them down to give you an idea:

Couldn't fit the rest of the lower plates, or the back plate in frame so this is all you get. Hopefully I'll have all the plates trimmed by the end of the week. Then there really isn't any option but to buy the flightsuit/vest and get forming! I plan on trimming, forming and fitting all the plates before buying the helmet, then I'll paint and weather it all in one go.
