I too find float loading helpful as a feel and a drill, but I am not a float loader by nature so I don't use it in my 'game' swing. Have you tried really consciously drag loading...get the the top of your backswing (wherever that may be, works well with acquired motion for a start) and pause.
Now pivot while making a conscious effort to leave the club and hands behind, start without a ball and focus on feeling the loading on PP#3 on the way down...really feel it...once you have that bring a ball into play and continue...really exagerate leaving the club behind as a drill...see how that changes your normal swing.
Float loading can be an answer, but it is not the only answer.
