Yeah, you don't want to remove a lot of wood real fast. You just need to work on getting your limbs even, and slightly starting to bend so that you can see where you need to remove the wood first, and then once you see where it needs to come off, then you can worry about what to use and as you can see, there are a few options for that. I like a file because you can work one small spot with it at a time, and it only takes off as much wood as you want it to, depending on how hard you press while you work it and how long you work it.
