Nice work on the hook up mate, what you should do really is rig your rod at home set your drag up and have your hook hooked on something and walk backwards with the rod pointing directly at your hook and slowly wind yor drag till your line pops, re rig and back the drag off a bit and te test and make sure the line doesn't pop.
Then when you fish leave your drag, don't touch it at all there's no need to it's set and no matter what that fish does unless he gets you on something sharp, you know te line won't pop.
