I'm on leave right now because we just had a baby. Spending 99% of my time holding the screaming poop factory while sitting on the couch. Not much to do besides read the forum and watch youtube. Luckily my wife let me out of the house for an hour to go to the roadshow
I'm in Michigan so similar climate. Just built my own pole barn / shop. Also went through this whole debate. There s no doubt that the spray foam is the best but I decided I could not afford it. I put radiant heat in the floor and have 16 ft ceilings. I went with fiberglass 19 in walls 38 in ceiling. 2 ceiling fans and windows up top keep good air circulation. 2 summers and 1 winter down and I've had no issues. The high ceilings and fans keep it cool in the summer, don't need any AC. No condensation issues or problems holding heat.
