As you gain comfort with the moves involved in this maneuver, you will be able to do this transition readily. These nuances are all a bit scary at first. Exercise caution and get used to going from the drops to the hoods to the bars and reverse. In my experience, it scared me half to death to change position on the bars the first times I did it, because it feels so unstable. It's just all part of our craft you'll learn with experience.
