I personally would go for the snapload. Then again maybe a 3 ring. I have used both for albums with more than 50 pages. The snapload could get bulky and the 3 ring can snap open.
I do yearly albums, meaning that an entire year goes into an album. I don't seperate holidays or special events. I end up having 2 albums per year. Each album can have anywhere between 75-80 pages.
It is totally upto you. Maybe make your lo's first and then see which would be best.
