We had new gutters an whatnot installed about 5 years ago and I bought the plastic ones and diligently put them on every inch of trough. We have large oak,maple and pine trees on all sides of the house so we have tons of leaves and needles.
I found it to be a total PIA to clean them clean with the guards on. I finally just took them off. I just use my leaf blower a few times a year to clean them out. I follow up with a good flush of water from the garden hose. Our house is 2 stories so it takes a good hour or so to complete but I have the time so I can't complain.
I'd box them up and send them to you but you'd hate me for it.
