Would ya, should ya?

I think Allen have moved this concept forward a little ... I suspect the success or failure of this system is in the subtle design of the socket to make the "hooking" (or balling) in & out easy whilst making sure the ball does not disengage when the crew is squirming about on the wire ...

My only experience of QR hooks has been negative when a hook released at random whilst I was on the wire ... it went straight in the bin at that point.

ditto- although my P&B harness (hanging in the garage for 5+ years now) has one, I always carried a spare hook onboard having lost one on my 600 and had to sail back 'hiking' from the rack.

sadly not- we are all desk experts, so no longer rely on the professionalism of the local chandler to ensure the clevice pin is the right diameter for the loose crown we find kicking around the bottom of our Musto  & Hyde sailing holdall.

Instead we order one off the internet, pay an additional fiver for shipping and then discard it as it doesn't actually fit despite, what we believed, was careful research across sailboats, P&B and the RS parts store.  Some guy on the Y&Y forum gave us some sage expert advice, but like the rest of them on there it turns out he's just full of sh*t and misinformation.  (It later transpires he 'works' for one of the clevice pin manufacturers updating their Facebook page with genuine user feedback, someone will call him out for it soon enough) 

We then lash whatever needed shackling down with a bit of worn out spectra core barely suitable for holding up a tramp's piss-stained troowsers, safe in the knowledge that even if we have a generous PY, our poor performance excuse is locked and loaded.... all cursing under our breath whilst updating our iPhone* task list to re-order a complete shackle Monday morning, parsimony averted, as it costs twenty quid.  

nope, rather good actually.  I was even nice about the RS Aero.
