Do I really need an outlet on both ends of these runs or using oversize gutter and downspouts can I only exit on one end??? whats the 'best' slope end to end of gutter? least slope?
I'd have 2 outlet for that length of run. At an 1/8" per foot, if you had one outlet the drop from side to side would be 4". With an outlet on each side, only 2". I don't like a 4" drop for 2 reasons. The visual and the time it takes to get the water from one end to the other in a heavey rain.
The oversize gutters will address the water volume but not the visual.
