Only the case when too much copper is bad, is if that patch is RF power loaded so it may radiate. All other cases, as bigger, as better.

 

dendad: ""design look good. 45 degree bends seem better""
Sure, the good look is must to be, but story about "bad" sharp angles of patches are coming from the same RF craft. Just RF are well reflecting thus any sharp angle makes multiple unwilling resonances. For ordinary frequencies its non-important.

 

Back to the original question, it popped into my head that 20 years ago our company produced some rather complex battery boxes to power film cameras and lights in crash cars. The total draw was 100 amps, and the reliability had to be at least 100% because a crash car for safety testing is very expensive. The boxes were unfortunately designed by an outside contractor prior to my joining the company, and they had "some issues", which were all related to voltage drops at every point in the system. The box used three 7 amp-hour lead batteries and a 24 volt regulator . The loads were 4 "helicopter floodlights" drawing 15 amps at 24 volts, and two film cameras, each drawing 20 amps as they spun up to speed. The circuit board traces were OK for both voltage drops and not burning up, but every AMP connector pin pair had an easily measured voltage drop of at least 0.1 volts, and another drop with the wire connected to the pin, crimped and then soldered. So at 100 amps the system only could supply 23.9 volts. Final checking was a real pain because while those batteries could indeed provide 100 amps for the required time, they could not do it very many times.
My point is that at those current levels every part of the system has a serious voltage drop that must be considered and dealt with.
