My favorite albums are post bound. I have tried the strap hinge and do not like them at all. They're a pain and I do not like that the page is attached to the book and you put the cover over it. I would rather the protective cover be attached and you slip your pages down in them.
I thought when I first started scrapping that I would like the 3-ring albums but decided I didn't like my LOs spaced so far apart in the middle.
