I am not sure what is meant by the fluke angle ?
If it is the angle between the shank and the fluke....
Than, Spade infect has the biggest Shank to Fluke angle..... And bigger fluke to shank angle does not help setting ability but hurts it....
If you think ability to set in hard to penetrate bottom is not important to you you are right you should not be impressed, but if you want an
anchor that sets everywhere an
anchor you can count to set in an emergency even at short scope...
Than you should care....
