Best choice? I use "Momentum" from Thruhiker - about 9.5 with DWR - for both shells. Even high volume down contains some small quills that will poke right through the DIY Tactical fabric. I ran a test on it with 800+ down.
That DIY Tactical stuff really sucks. I liked the coyote color so I ordered a bunch thinking I could find a use for it. So far the only suitable use I've been able to find is outside pockets on SUL packs because it just won't hold water at all, so it drains as fast as mesh and is a little lighter. The only thing I can't figure out is why it weighs so much even though it is less substantial than Momentum.
