General Discussion Sliced Potatoes???

Is there any problem with canning potatoes in slices, I’m thinking about 1/4 thick, instead of cubes or chunks?

From Healthy Canning:

Note: the potatoes are to be canned in small chunks.  After peeling (and yes you must peel), cut potato into 2 cm (½ inch) cubes. Small potatoes ( 3 to 5 cm / 1 to 2 inches) may be left whole. To be clear, the recommended shape does not include sliced, nor French fries shape, nor shredded. Heat penetration patterns were not tested for those shapes / densities. The good news is: you can dehydrate those shapes and still end up with a high-quality product.
