My grandad use to do alot of kitefishing al over and blackbag floating off north pier.. The off shore wind's normaly blow early morning's and die's off as the day go's on, just remember on cold day's or if the water temp is cold to set the trace to float deeper because fish wont rise to the surface of cold day's to chow , the sea must not be to big or to chopy... Yellow balloon's should work for sighting long distance.. Good luck hope u get some of those early kingy's 35kg job'z..u need the right off shore wind or else it will be ver difficult to float it out.
