Freestyle Hand Entry Position

Is there any consensus on the correct postion of the hand at freestyle entry? On the one hand I have read that the hand should be angled slightly palm-inward toward the body at entry (third or fourth finger entering the water first), but have also seen the reverse suggested (palm-outward, thumb entering the water first). Palm-inward feels more natural to me and seems to put less strain on the shoulder, but I can see the advantage of palm outward in terms of preparing for the catch phase and keeping a high elbow.
