How "thick" are the different H agendas? I'm thinking I may need one. (I have a Franlin Covey- it's cute I promise!- but it's so massive that I put that and my wallet in my herbag and the thing is stuffed almost to the point of not closing. And they say it's pocket sized! ) The Ulysses seems to be the most popular style, right? Any practical reason for this, or just because its the prettiest or most readily available?
