My patties are soft & they squish, This is a huge labor savings by being able to put 4-7 pound patties on at once, also, you can hit the heat ring cluster with a soft 5 pound patty but you can't do this with a five one pound square patties.
Now, if you have ten hives in the back yard the square patties are a perfect way to go, but if your like me with thousands of hives the soft patty is the only way to travel.
I can put on 1500 pounds of soft patties by myself a day, know fuss no muss.
The hard square patties are made for pallets & shipping, not for the commercial keeper in the field.
P.S. the avg hive goes threw 75-100 of pollen a year, and that at 26% protein so you guys do the math.
