Interesting idea! I haven't fished since I was a kid. What is
"shock" leader?

...Jim Thompson
It's heavy mono filament (60lb+) that's used to take the strain of the
cast when you are using heavy weights for beach fishing. Two rod lengths
attached to the main lighter line is plenty to take the shock of casting
out a 4oz lead from behind your back. It's rather undesirable to have
4oz of possibly spiked lead flying uncontrolled because your main line
wasn't up to it. (Spikes to grip in the sand against the tide)

I'm almost certain it's just 60lb+ mono filament line sold in small
reels and can come in all sorts of funky colours as well as clear.

Reminds me, I must go fishing again....
