Using .33 oz cuben for baffles is only stronger if you fold the edges and sew through the doubled layer. With nano-see-um type mesh, if you can sew straight, it's unnecessary to roll the edges. Sewing will be a must, taping or bonding wont give you enough peel strength in any configuration I can think of.
Tearing is only a concern at the edges, and by rolling them, and thus doubling the material at that spot, they're much stronger than mesh.
Linear baffles would likely be more expensive, since you would need a longer piece of cuben to cut the long strips. Say 2 yards atleast, where-as you'd probably only use one linear yard if you cut them for lateral baffles. Radial baffles aren't necessary on most quilts, and honestly, unless you're making a really cold weather bag, I don't they're essential there either, you can just cut straight strips for lateral baffles also, so i don't see the point unless you just want something that looks different. Another disadvantage of linear baffles is that you'd only be able to shift down from head-to-foot, instead of side to side.
