I'm building an AR9 pistol (may be SBR'd later) and am looking at options for the buffer tube. I've narrowed it down to either going with a KAK Blade or Phase 5 Hex 2 with the foam cover. I have a Thordsen Enhanced Buffer Tube Cover on another Form-1-pending pistol and like it but want to try something different.

The Blade is pretty popular but I'm hoping some of you have used both types and can provide feedback on usability of both. Thanks in advance.
