Andrew, please give me an indication of what level of proof you wish me to provide - you seem to require a still warm body to prove the point.
I have provided links to an article by David Bowyer on Difflock (an authority on offroading) that supports the notion that using a towball as a recovery point is a reasonable thing to do - and also to an article that proposes the use of a locking shackle on a towball as a safe and strong means of recovery. The article contains test results that support the notion that a towball can provide a stronger recover point than is usually provided by recovery hooks often installed as standard on 4x4 vehicles. The article also provides support for the strength of materials data that I posted earlier which indicate that disintegration of a towball is unlikely to occur.
Up tp press, you have made a few assertions about the unsuitability of a towball as a recovery point for any kind of recovery and have provided only a single link to an article that doesn't provide enough detail to support what you have said. I would certainly be interested in any documented cases of towball fragmentation that inform your views. I certainly haven't seen any.
Cheers
Andrew
