Making a Jon line. How do you stow/carry?

[Fastmarc]

Recently I found myself in a situation where a Jon Line would have been handy. End of a dive in choppy seas, a drifting anchor line and a crowded safety stop. The line was bouncing quite a bit too.
So I'm putting together one and I'm wondering for those who made their own how do you carry it?

I use a spool and bolt snap that I keep in a pocket. It can also be clipped off on a D-ring.

I have a Jon line hook on a long line with a clip on the opposite end.
The line is long enough so that I can be behind another diver at the same depth.
It is stored shortened using a chain sinnet knot, the knot is retained with a double ender. The sinnet knot shortens the rope making it about a meter long.
The line is stowed in a small pouch on my waist band, with the bailout tables.
The line is also quite heavy, about 5mm diameter (1/4").

Under normal circumstances, I use it shortened. If its very congested on the stop i release the chain sinnet, allowing to float behind the rest of the divers.
I alway carry cutting tools, I have come close to having to cut the line in very strong currents where the hook has jammed so tightly in to the shot line that I have almost been unable to release it.
Be careful, I have seen people get the jon line wrapped around stages etc.

In an emergency I have used a reel and a couple of double enders. Its not an ideal solution, but has served a purpose in an emergency.

Thanks for the replies.

That Jon line setup looks pretty technical.

I was just planning on using a strap about 6' long with a spring clamp on the end.

In big currents it can be a real blessing, especially if you have a reasonable amount of accrued decompression time.

Ideally in a big current I prefer to either 'bag off' or use a trapeze, that means you avoid having fight against the current. It is not always practical and safe to do so, ascent up the shot line might be required, then a jon line is a real blessing.
