I got that very same dilemma a lot. I realized that Judo and Jiu Jitsu are really two sides to the same coin. A great deal of Jiu Jitsu techniques have Japanese names and are a part of the original 40 techniques Jigaro Kano had created. I understand wanting to go where is comfortable and that is using Nage-Waza to make openings into your Katame-Waza and finishing there, but when you encounter those that take you out of that comfort zone, it's time to evaluate your weak areas and more them strong points like Bobby was saying. Fly over passes and pressure passing should come pretty natural to you since Judo constraints on the ground tend to be limited so you have to work quickly. Since your a black belt I am sure your top game and pressure is pretty solid, so passing I agree would be a great area to work on.
