round vs square

[Bentley Wood Maple]

Where is the advantage of a round stack? Would be much easier on my limited fabrication skills to build my SS base stack to take a 10x10 square SS stack/stovepipe.

If you're building your own stack it would not matter. I do not know where you would buy square stack.

A 10 x 10 square stack will have a lot more volume than a 10" round stack.
