Big Flies = Big Fish

My friend, Drew Chicone, has a theory on catching large Snook.  When presented with a big easy meal drawn right across their nose these fish will eat even when they are not hungry.  I'm fishing 2-3 inch patterns on a size 4 and Drew is throwing 5 to 6 inch flies constructed with Yak Hair on a 1/0.  Is he right?

I think he's got a point!
