Replying to Hand drag 3's

so i was fooling around on sat and went for my first hand drag 1 and it was a really cool feeling and i got them down (but not at really fast speeds yet) and i was wonderin how to go about doin drag 3's. i have seen vids of people who use two hands and shoot their legs out really high and i could picture myself doing that pretty well. or i could set normal drag harder. which one is easier/safer? or any tips on how i should go about doing it.
