Can you post a pic of what you're working on?

Just want to get something up there with a minimum of work. The attic is 80' by 30'. Its about 150 batts but I'm only going to replace the bad ones for now, maybe 50.
I'm not doing spray foam or anything that will be tough to undo like glue.

No channels, no mess and restruction. Air will flow just fine and find its way out the ridge vent. Its designed to do that.

Cut what? Solid foam panels? They're pretty expensive. And cutting them would be a giant pita.

Then the insulation goes on top, between the rafters.
At a minimum, you’re going to want to do something at the soffits, to allow air to flow
You can buy a M12 Milwaukee battery on Amazon for $28 or four knockoffs for $40. I have two and they work just as well as the originals.

Yes, those channels exactly. Except I think mine are plastic.
I'm pretty sure I just want an air stapler. How would I control the power with that milwaukee battery thing? The wood laughed at the stanley/bostitch pos that I had before. What is the benefit of the milwaukee thing? Its lighter, easier to maneuver and no hose? I guess I'd love it if it didn't suck but I'm skeptical. Is some weird hangup I've got. I've used/borrowed plenty of battery tools and I'm just not feeling much love toward them. Probably because my friends all gush so hard.
Anyway, I think I know what I want: a 3/8" t50 air stapler. I'm going to walk along with a helper, they hold the channels and I staple, then we do the batts. Finally I'll cover with some rolls of sheeting to keep the batts from leaking into the attic.
