I’m sure FMJ cables are good but cost a fortune…
You’re right – any decent outer cable will do the job. The important thing is the ability of the outer to resist compressive forces. The FMJ is as close to incompressible as you can get in a cable outer. Nokons come close.
The less compression in the cable, the more clearance you can have at the pads. I suspect people who have problems with BB7s are using soggy outer cables.
I use Jagwire or Avid outers where possible, mainly because it’s difficult to be sure what is the quality of the generic cables in the reel at the lbs.
