The channel from the soffit to above the insulation is easy--you get it in
premolded plastic from Home Depot for not much money.

It's called Accuvent. We installed a bunch of it on a current project.
Local Home Depot didn't stock it, so had to order from HD online and
pay some shipping. Neither Lowes nor Menards has anything like it.
Goes up fast and will work with R30 easily. Highly recommended.
