RE: Input wanted on "Oust Composite" carbons
Methinks someone bought out CAE. Those look like CAE arrows, specs, names, etc.
I believe most of them are made in Korea, if that is a concern of yours.
I used the CAE X-caliber fluted arrrows for a few years. They did shoot well and performed adequately on game. They bend easily, and are somewhat brittle compared to Easton when you try to straighten them. You can straighten them by looking down the flutes to check them though. Harder to straighten on a conventional aluminum arrow straightener due to the flutes.
I think they may send their "cull" arrows to Cabelas. I had some of the Cabelas SST arrows (skinny carbons) and the durability and wall thickness uniformity left a lot to be desired, but I have been told that the Cabelas arrows were CAE's 3rd or 4th quality shafts.
