chocobo digging

I am currently an A10 digger with the blue silks for time increase and I also have the bore on my chocobo to dig more less common items. I have worked really hard to come this far, and I found myself disappointed. It seems like I dig about the same as when I didn't have the blue silks and the bore command. I was hoping maybe you could help me out and in a future update give me some glory. maybe a lot more time, or better items like more petrified logs stuff like that. I put in hours to raise my chocobo and to level the digging and the racing on another chocobo to get to this point, and I was just hoping I could get more fun out of it. thanks for what you have done on the game so far its the best thing in the world. I love it every day all day when I'm not at work. I appreciate everything hugely. I pray you can help me out on this one, because the time nerf from years ago ruined all my fun. I used to dig all day long everyday, and I don't sell anything for personal profit, I just enjoy the chocobos.
