Heya Matt,
The finished Flavor 4, with techflex is about
1" [Correction Here: After checking I found it is actully closer to 3/4" or 19-mm] in diameter....VERY Beefy...looks similar to a garden hose to me. It turns out to be a rather badass looking cable in my opinion.

(I'll confirm that when I get home and if I'm off by much, I'll correct myself in a later post.)
OK...here's a buncha hemmin'-and-hawin' and saying alot without giving a solid answer.....

I apologize in advance for my equivocation on this one.... Yes, it can be difficult to get it bent into rather tight corners though may be possible if your gear is not too light or on rollerballs, (or vibrapod cones). It is a bit more flexible than one or two other heavy gauge power cords I've had a chance to try.
Duster or others (maybe Chris VH himself?) may be able to give you a better feel for the flexibility relative to other power cords....
I'm not sure if this is a good idea or not, but by cutting the air-hose a bit shorter, thus leaving a relatively short length (~4" or so?) of the star-quad cable "exposed" (it's still insulated!) at either end can make the ends of the cord much more flexible....though this may somehow impact the sonics in some esoteric manner (though I have no idea!!). But that's some of the fun with DIY (for me at least)....try it, don't like it, try it another way...'till I dig it.
Yeah, I do enjoy how easy it is to work with the Furutechs and the strain relief is truly that...a strain relief (for me

) Sorry, couldn't resist.... Yeah, would be nice if it was the standard....I definitely dig-it.
Something else that I've tried.... I used ProGold on the ends of the wires before inserting them into the outlets, plugs, and IEC ends. Not bad... months later I snipped the stripped ends off of the wires, re-stripped the insulation and then applied a small amount of the Walker SST to the wires and reinserted them into the outlets, plugs, and IECs....Very nice....though, obviously one must be
VERY careful as this 'paste' is conductive!! So the potential for a short

is a very real possibility if one isn't extremely careful. At some point I may re-strip the ends of the power cables and try a different contact enhancer. Looks like my power cords may just keep getting shorter and shorter if I keep trying different stuff

Best!
Doug
