this is... ONCE AGAIN... an issue of Economics and not one of scientific relevance. If anyone wants to spend 500$ on a machined billet aluminum bracket when a 10$ stamped steel bracket can do the same work, why should we not be allowed to use Billet aluminum? Common mass mentality is that you've wasted 490$ when if fact you merely made a decision based on economics.
if you want beautiful stranded and woven cables, by all means use them.
in as far as 'expectation' bias... I have a different view point. if I am choosing to use something that costs me inordinately more to use, my 'Bias' is not one of justification, but one of criticality... In other words, I am actually going to be MORE CRITICAL of that item, not less critical.
