The thinner you try and make the cable the greater the corners you
have to cut. But which of these do you reduce?
The sheath is important where (super)flat cable is to be run under
carpet, as is the conductor and insulation on each wire. No easy
answer.

Well, super flat uses #28 awg wire. Commodity CAT5 is #24 awg. CAT6
is #23 awg. The #28 awg isn't a problem unless you need to replace
the crimp on connector ends, or you need to run DC power through the
cable.

I've tried using flat (not super-flat) CAT5 under carpets. The stuff
rolls over as the rug moves and eventually creates a lump. Carpet
tape helps, but it still doesn't last. I recently received some flat
cable designed specifically for under the carpet installs:

Note that it's #24 awg wire, which means it uses standard connectors.
I'll be replacing the lumpy CAT5 shortly and expect it to work better.
Note that I have to notch the wings in order to make a turn.
