The deck at my old house was was decently structured, but after a year or so, several of the boards twisted and made the whole deck look like it was built with pallet grade lumber. Spent a few hours doing what you did and replaced those pieces. It's amazing the difference it made in the whole look and feel. Not to mention the deck builder used common nails instead of ring shank, so kept having nails pop up over and over, went through about a carton of screws replacing all of the ones I could. I also agree with Ted's comment, nice to have the right tools for the job.
