thank you for the opinions guys. I pretty sure im goin round tube soley because i got a good deal on some this weekend at an auction. 20ft. sticks for 20 bucks each. So slowing the airflow thru the heat exchanger is desireable to increase thermal transfer???

Hello everybody. i have been lurking around here for a while just learning. I have been planning out a gasser build in my head and have even picked up a few materials so far. my questions are.
what would be a good diameter and  wall thickness to use for my heat transfer tubes? Second is any opinions on using a round firebox versus a square one? is one better than the other. Thank You for any input
