that last one looks nice, what did you cut it at 3.5"? I also double cut, whatever lawns need, it, some I will just raise the deck, and go over the lawn the same way I cut to break grass clippings up, others I cross cut, especially if the house is on a corner of two roads that see a lot of traffic. cutting the same direction for 2 weeks really helps strips stand out....
