Unsound - I don't know much about particular products. What little I do know says that for braided wire to work as designed, it must stay extremely quiet internally, and that's no small task. Straightwire's Bflat (I believe) preceded Wireworld's entry and was abandoned due to those difficulties (near impossibilities) of keeping flexible strands functionally rigid. Kimber filled the gaps with silicone which had to be applied to each strand and then rolled to form a filled web with no thick or thin spots. Sounds tedious.
I know that Jim ended up with Goertz flat wire (late 2000s) as his best, affordable and reliable solution. Please tell me more about Alpha-Core's approach.
