OK, thanks Gary, that helps me to see what you're looking for.
First, I'm not completely tech savvy, but not too bad. The pages that took a scroll down to load, I thought it was me being impatient! Don't like those as much.
The 30.3 CA-CZ, the PDF, I like that because as you said you can pop it out and zoom and what not. It is also clear to me, as in focused, easier to read.
