Hi all, I am on a green day. Can anyone tell me what weight of raw king prawns i can have as a B Hex. Is it still the rule that if you find the syn value of meat/fish or shell fish you just have to deduct 6 syns to use it as you B Hex?? In my book it says 100g raw is 4 syns so can i have 150g which would make it 6 syn? Hope am making sense lol. Thanks
