Something is really bugging me and I am hoping my C&V friends can help me out with it.

Last night I came home from work and went immediately to the basement to work on the Team Miyata project I recently posted about.

As I came down the basement stairs I heard noises coming from the rec room beside my shop, and when I cracked the door open, I saw my wife in flagrante delicto with the guy next door, a guy who I would have considered one of my best friends. Right there on top of the pool table.

They didn't see me and I didn't know what to do so I crept away and went into the man cave. I spent all night just staring blankly at the stripped-down Miyata frame.

Now my question:

Should I update the drivetrain to 10sp STI or stick with a traditional DT setup?
