Ready to insulate a new home
I am ready to insulate a new home, and need to make a final decision. I need help.
I have been the recipient of many helpful tips and guidance from thes pages as well as other green forums and it's all kind of coming to a head in our new home build as I attempt to make a decision about the insulation we will use. Here is the specs on my houses wall stack up
LOCATION: 47460 On the line of upper climate zone 4 and lower 5
2x6 exterior walls, 1/2 inch sheathing with tyvek, 1.5" polyiso foam with taped seams, vinyl siding
I am considering the following insulation approaches and need some help makign the decision
OPTION 1: 1" closed cell flash in stud voids then wet sprayed cellulose
OPTION 2: 1" closed cell flash in stud voids then ruxol or fiberglass batts
OPTION 3: 2" OPEN CELL in stud voids and then batt or wet sprayed cellulose
OPTION 4: Full Cavity Fill with Wet Sprayed Cellulose
Please give me pros and cons for all the options, I am mostly concerned about the moisture control in the walls. I do not want to cause problems by allowing moisture to get trapped in the wrong place in the wall stack up.

Since drywall has a permeance of 0.02 liter/sec - m at 75 PA is ever possible to have sheathing dry to the interior of the home?
