Sounds like you want to do the big floater, not a little one. Ray Peters taught me on a hill, in 2nd gear. Anything involving a wheelie is easier on a hill because the hill does half the wheelie for you.
Keeping in mind that the bike is steered with the feet, initiate the downhill turn with the inside foot, pick the front wheel up, bring it around, then shift your weight to the outside as you near the competion of the turn.
On the small floaters, practice moving the front end over 12-18 inches with just your body, not the motor. This helps you land balanced and continue making the turn after you touch the wheel back down. Maintaining balance after you make the move is the critical part, not just the move itself. Once you can do this without power, try adding some power to make the move bigger. Next thing you know you'll be doing bigger floaters on flat ground.
Then, go try it in a section. That is where the smoothness and balanced you acquired from the small move will come into play.
Good luck,
