Topps Super storage suggestions
 

Does anyone have a good suggestion for storing/protecting Topps Super cards (ex. 1970, 1971)? I am concerned about using the 5x7 toploaders I have seen because the thickness of the cards could create a problem over time. I know I could have them graded and slabbed, but I really like raw cards. Any suggestions are appreciated.

I forget the number but there is a Cardsaver they fit into and then you can store them in two pocket pages.
