Good point Jay. I'm sure we all strive for uniformity and a one size
fits all solution, but I agree, in the end every site is unique and
requires custom solutions tailored to its actual conditions. 

Always appreciate your thoughtful take on things,

One issue that has been troubling me is the 1 size fits all.

We live and work in many really different environments.

Because of this, what works here might not work there, but just  
because it doesn't work there, does not mean
that I shouldn't be able to use it here.

Lets look at the the desert regions vs Hawaii.  In the desert rust/ 
corrosion just isn't a problem so braided wire isn't going to be a  
problem.
Vs hawaii where maybe only solid wire, let alone stranded is the only  
choice.

So I think that our industry is getting really far down the 1 size  
fits all path and i see that being ineffective, expensive, and throws  
creativity out the window.

Just my 2 cents.
