Although it is now "calendar winter" you would do much better to wait for good "winter conditions", ie cold, frozen, low avvy hazard - instead of warm rain and isothermal avalanche prone snow.
My knowledge is empirical while yours is theoretical. Or hypothetical. Or even fanciful.
try it sometime. It's easier to get a flat sheet of ice to fracture than it is a rounded piece with a diameter equal to the width of the flat piece.
Thank you for your valuable contribution CBS. NOw go back to discussing something you might have a clue about It is easier to fracture a flat surface than a round surface and a round surface is easier than a pointed surface - basic mechanics. Try it sometime with an icicle!
