According to the Taz I must do Tzli if it was Moilich from one side and twelve hours past Because Hefsaid does not help me here since I COULD do Tzli instead if Bishul and avoid all issues. But I could use the same argument by any case of Hefsaid Meruba and tell you to sell it to a goy?

How can we say that on the one hand Tzir is sharp and makes Kvisha Happen much faster but on the other hand it helps cool down the salt that is on the surface of the meat? 

Why did not Rav Dimi crush his salt? 

If we only salt from one side and 12 hours pass we need to do Tzli. But why can't we just salt the second side and put the piece of meat down on that side. That way the salty blood won't have a chance to get to the side that has already been salted?

If one is Chayve Misa for breaking Shabbos how can his Shchita be good if he looses his status as living human being? 

Can blood that came out from Melicha make something else Asure?

According to the opinion who holds that the blood is too "thin" to go in does he also hold it would be too "thin" to come out? 

If Tzir is going to still come out why should we care how fast it's coming out eventually everthing will come out?
