I've been thinking that I should hang the gutters with the gutter guards in mind. I think the best guard I've seen are the aluminum mesh that was tucked under the roofing shingles and installed with some slope. That is the plan for my roof. I also use brackets with stainless screws so I need better than 1" between the shingle and the gutter for some access.
1/8" per foot drop may look too much with long lengths, but it is a must. The solids that don't drain becomes that much harder to clean after the years.
