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...

by turning it down into bullets)
