Phil,
I did use a combo of EVOO and butter. I also had the fish at room temperature and they were filets and not steaks so they were actually fairly thin.
I'm thinking the mass of a cast iron pan along with the factory cast iron grate is just too much for the BTUs of the grill. I'd be interested to know how your blackened fish comes out on the Weber griddle. If it works out, then I'll probably drop more $$ on another accessory!
