Albert Eisentraut was one of the first proponents (in the USA in the late 60s to early 70s) of mixing tubing gauges within a frame, to match the frame to the rider's strength, weight and pedaling style. For a large comfortable frame, he would often use heavier tubes on the bottom, i.e., forks, down tube, chainstays (and maybe the seat tube for a real animal) and lighter tubes for the top tube and seat stays. I have built frames that were otherwise identical to each other, but with one using this tubing lay out vs the other one being all SP (heavy gauge) tubing and the difference is significant. I've also found that deeply V'd aero rims transmit a lot more road shock, (as do clinchers in general) when compared to a sew up rim of the conventional pattern.
