You can try it but there's no guarantee that you'll get the book.
Theoretically the 18k has a higher drop rate because there is less stuff in there. I would offer to crunch numbers but I just came back from a 3 hour class so I don't want to do anything right now x_x.
but in the client files both 18/24k has a drop rate of "1" for masterhands, meaning it's a 1 out of the total (whatever it happens to be).
