Excellent cable for its purpose but I cannot see anything startlingly wonderful about it for general audio use?
Core to shield capacitance is a fairly common 180puf/mtr. It has a nominal OD of 6.6mm so it is going to be rugged but also I suspect a bit stiff and "clunky".
For good working you will need a spike, a big needle or grind down a terminal driver. Then unpick the shield and twist it tightly. If there is a lot of it and it is bulky there is no harm in "thinning it out".
Once teased out MAKE SURE you have no stary strands and then tin the whole thing to keep it out of the *&^%in' way. I would heat shrink an overall sleeve of about 15mm in length to tidy it all up.
I would not pay a premium for this cable, I bet there are plenty as good and cheaper.
I have some patch leads in Belden V 9534 foil shielded 2 pr. Excellent stuff but I didn't BUY it!

I think the main thing that irks me is that it seems a massive faff just to strip and clear all the stringy/twine stuff out of the way. Seems to involve a lot of precise Stanley knife action.
I'm going to have ended up making about 25 patch leads by the end of it. So after 50 or so connections I'll probably have found a few tricks here and there
Another thing while I think on - it seems that most cables like this (i.e. shielded 2 core) seem to only ground the "amp" end of the shield. I get what they're going for, and I'll probably do the same myself, but I'm not sure it it will may any difference at all...
Any thoughts?
I have a ton of Belden 8412. I was given a reel of it about 10 years ago and kept it for either my own personal projects of for friends and bandmates and funnily enough am just coming to end of the reel. It's is fairly hardcore and stripping it is a major arse pain and hard going on the hands.
For long runs on tough tours it is pretty hard to beat. A couple of time my whole pedal board has used it but I don't particularly like if for that purpose because it's chunky and don't want to flex too easily it tight spaces but it is very good none-the-less. With a simple 'U' patch lead you want to make sure that both pedals are anchored well as it puts pressure on the mounting.
As far as stripping goes, despite using it for years I am yet to find a particularly easy way of doing it. What I do is slice through to the woven layer - you can be pretty firm as it doesn't let much through. Once you've removed the rubber and foil I unpick the woven layers down to the cut, twist all the strand together and then cut them off as low as I can get down. From then on it's just normal cable.
On your board in something is a tight squeeze I have used cable tie across the 'U' shape to take a bit of the strain.
One thing to definitely remember though is to think about where the patch leads is going and what angle it needs to be and get the jack lined up before soldering as it's a bugger to twist and is so tough it end up weakening the jacks long before it would give out.
I've already made a lead that although looked beautiful, wanted to bend the wrong way around, so I had to re solder it (and now it isn't as neat).
Good job I'm not in a rush
