I personally like my cards in individual Card Saver 1's. Now, I don't have as near as many cards as you all here so it is easier for me to have them this way. I always found the sheets sagged somewhat and cards could get bent.
Plus, having them in Card Saver 1's is the closest thing to having them as a kid in piles looking through them one at a time and being able to handle them without damaging them.
All that being said, for what it is worth, I am working on my second set from the 60s, 1967 Topps Football, raw. I picked this set because it is the year of my birth and I love the old AFL. Plus, at a 132 cards with the limited funds I have, makes it a very doable set for me.
