Thanks for the link. Looks dangerous, sounds very noisy. I'll just work on zone 2 alignments a little more instead. Safety first.

I don't think its that dangerous. Not much more dangerous or nosier than say using a Speed Stik or swinging a club.
When I was down at the Swamp, Yoda showed me how to use the the Speed Chain and it does teach you a lot. For example I have a habit of dragging the club way inside on the backswing but do that with the chain and you end up hitting youself with it and on the way through you can't whip it too much from the inside either as again you will end up hitting yourself.
For me it taught me how to really use my pivot (for a swinger the pivot is where all the power comes from) and I could really feel that I could trace that planeline really well. On the way through impact and to follow through I could really feel that I was 'dragging a wet mop' and I could sense the lag pressure in my number 3 pressure point.
