Crawfish boil help

Grill your sausage. The grease from the sausage makes the crawfish taste crappy and makes your leftovers all taste rancid.

I'd take it one step farther and not add the sausage at all. Why throw sausage in the boil at all? It loses all its flavor and tastes like crap. I would grill it too and serve it as an appetizer. Why ruin good sausage by boiling it? It's a waste of money.
