I know there are plywoods that are intended for this purpose, with an attractive face and often cut grooves to make it look like board-and-batten or other traditional vertical sidings. T1-11 is a common example. My friend used Breckenridge on his house, with 1x battens over the seams.
However, if I'm not interested in the appearance of fake vertical siding, and will tolerate a less-than-perfect surface, what other plywoods can I use, to save money?
Suppose I pick through the CDX pile and find some with a nicer-than-average C face. Would that work OK in this role?
