    Why?
    Any data to verify this, or that overall performance is better 
with tubing?
    I've often thought about it, and I wonder if the thermal mass of 
the solid bar more than compensates for the surface area of the 
tubing. My problem is getting motivated to purchase and hack up three 
feet of 3/4" copper bar to test next to tubing...
