I don't know why I am replying to this post but had a hard time resisting. You want to take a ball designed for dry conditions and attempt to make it hook more on the backend by sanding it? All I can say is no. Surface will get it started earlier. Your tactical would be a better option but since you like that core shape you should try to find something with a higher diff and intermediate diff like the Black Ops if you can find one. I'm sure Doom can add a better perspective.
