Found the last two pieces. Besides Turtle Rock I was missing two really easy to get pieces from Karaikko Village. As usual, I was so focused trying to grab the hard ones (like the ones from the mini-games) that I missed the easier ones.

Anyway, took down Misery Mire and completed Turtle Rock, which is still one of the harder dungeons in this game. All that is left to do is upgrade the Sword and Arrows a final time, and then Ganon's Tower. I've decided I'm going to fight Ganon fairly this time around. No screwing with him with the Bug Net, no using the Magic Cape to no sell all of his attacks while I beat him to a bloody pulp, none of that.
