I’m another one who prefers the large-flaked shavings. They add much more volume per bag then the fine and I use one bag to two of the finer shavings.
I’ve been doing the toss method for so many years it’s become second nature. Toss and toss until no more manure rolls down the bank, then pull the bank away from the wall and you’ll usually find a few more and you can pick those up individually. I then use a rake across the stall back and forth, which may pull up a few more manure balls, and you can catch those with the end of the rake and fling them into the manure skip.
