Never one to quibble with a pure pro like Max,but not everyone can handle a 14 inch.We find them to be very flexible and take a practiced hand.
Up to 16-18 lbs ,we amateurs seem to have better control with a 12 inch.
Passed down from Bob Milroy/TX Rib Rangers that 20 lb and up needs the 14 inch.Also from Bill,
when a packer gets away from you and gets too soft,the 14 inch can be pressed straight down thru the packer,rather than slicing and maybe breaking up the meat.At least you can get the slices in the box.
Now,when I grow up-maybe I can handle the 14 on everything.
