I got the books from the core set spiraled. Did anyone else do this? there are somethings I like about the spiral and somethings I don't. The spiral is nice because it lets you lay the book flat. I especially like this for the bestiary because it makes it much easier to track the attack powers. One thing I don't like is that it make the books much more floppy. If any one else has done this I'd be interested in knowing what you think

Instead of getting the books spiraled, I bought the pdfs and printed out the bestiary and other relevant pages to put into a three ring binder. That way I can mix and match for the evening's adventure.

Spiraling the books is a good idea though to get them to lay flat for other reference.
