Hi
BB,
Great words. I am, as always, in total agreement with you. You comments about
caution were simply sensible mate.
With respect to the 'two schools of thought'

Yeah, I understand that is the case
here. In my view, schools of thought become
entrenched, people are 'set' (pun intended) in their views, with little chance of resolution.
This does not prevent friendly debate, based on rational argument and evidence.
My personal view is that, when in doubt, always defer, and refer to the manufacturer's instructions.
I think my views are consistent with the view that was held by that great company,
Scott Bonnar.
All very sharp.
