I am a big Kelloggs collector and have always used the rigid top loaders for straightening. Never have had one crack. I've bought slabbed sets and lots with cracked cards and have always wondered how long after grading did the cracking occur.
Sadly, even more common than curling/cracking is the fading of the 3D effect. I distinctly remember how vibrant they looked right out of the cereal box and all have lost their original luster to some extent.
Oh and one more thing, these cards do not like cool, dry storage areas like basements during the winter.
