None of that makes any sense to me at all.  When I tighten down the 
screws in one of those buss bars the wire deforms a bit and there's no 
way it pulls out.  Besides, you can loop the wire twice through the hole 
in the buss bar if you're really worried about it ... you'll break the 
wire before it ever pulls out and it's a whole lot faster than your method.

And as I stated in my first post, these bars are specifically designed 
to accept either copper or aluminum wires ... it's stamped right on the 
side of the bar.
