That is one point Jim Barrett made in his series. He uses 1/2" plywood with 16" bracing throughout. He says it's to reduce vibrations, and I believe it is, but I've got to believe that's also why he's able to use 1/2". I see so many layouts with wider spacing, but it seems they all use 7-ply 3/4" plywood.
