Refridgeration tubing is much softer & easier to bend than tubing for plumbing.

This is the second time I have seen this comment about how hard it is to work with solid copper wire versus 1/4" copper tubing. I have worked with both quite a bit and IMHO, I have to disagree completely. 
 
I have found that the tubing is stiffer than the solid wire and quickly work hardens as it is bent and gets harder and harder to manipulate, until it sometimes becomes necessary to anneal it in order to continue working with it. The solid wire is much easier to work with. Now, I will say that I am comparing 6AWG and 8AWG solid copper wire to 1/4" copper tubing and the wire is considerably thinner, too.
