   This isn't an answer to your question, but it might be worth doing the math to see how the R-value of your 2x4 staggered stud wall with 2x8 top and bottom plates compares to a "Bonfiglioli" style wall of the same thickness. For example, 2x6 + 1" foam strip + 1x3 furring strip = 7 1/4", so it wouldn't require any change to the wall thicknesses or exterior details in your design, but might result in a slightly better wall (or maybe not, hence "do the math"!). Here's a link with more details on the foam strips thing:https://www.finehomebuilding.com/2014/11/26/breaking-the-thermal-bridge

   Too late to call an audible at this point. Lots of engineering already done for this particular wall setup. The project is moving so slow that there is no way I would change it now!
   Thanks

   I built mine with a staggered 2x4, mostly for noise. My advice would be not to stagger them, if I had to do it again, I would just keep it simple and line everything up. Pain in the @#$ to insulate with batts (dense packed would be easier but then you loose sound isolation in a double stud wall).

   I offset my studs by only 2" or so, this way with single top plate roof and floor loads are carried by both set of studs. Not required by code but makes it stronger. You will probably end up putting orphan studs on one side near rough openings, works but looks a bit strange.

   Good luck.

   Orphan Studs. I like that!
