re: Covered gutters, screen gutters, no gutters?

This summer I will be renting a ditchwitch and installing french drains that run down to the retention pond, which is why I was debating just removing the gutters off the backside instead of tieing the gutters into the drain system.

Also debating regrading the back as it has a natural hump in center that I think is keeping the ground closer to the house constantly moist, more-so than the front.
