I just got the wash manual 33rd edition from amazon and its spiral bound, I actually meant to get paper back (perfect bound) because I prefer that to spiral. But looking at this manual, its pretty huge, 1000+ pages and the pages themselves are fairly small which makes me think that if I returned this and got the paper back it would be really tight and tough to open the pages.

Any recommendations on whether to keep the spiral bound or just go for the paper back? I wish I could feel the paperback, then I could make a decision.
