Be careful on drag settings and DON'T in my opinion set them before you go....

Hi Nick, just think how many times you'll strip line off, false-casting or re-setting-up a shooting line on the deck - you'll soon get sick of pulling against XOS-stopping preset drag.
Also (trust me) its really bad form to get the rod pulled clean out of your hand. Try the preset out at home against a scale - and take note just how hard you are hanging on to the rod to pull 10lb or whatever, and even the braced body position you need to adopt. There's no way you can fish like that all day! After a quiet period, if you get nailed on the drop with only a meter or two of slack, Mr XOS (or even his little sister) will have that out before you even wake up, let alone get braced for action... Splash ...    

Right, thanks guys I can see that in my mind I was maybe imparting too much importance to preset drag. Thinking about it I've had trout clean snap 12lb leader on the strike in the Waitahanui mouth  ... so makes sense to not have a running fish hit an overtight drag. Cool, more food for thought.
