Yes, the correct balance on the saddle. Get the saddle positioned first.
I like this saddle position method video. The goal is to get the saddle where you don't either slide forward on the saddle or have difficulty lifting your hands off the bars.
The test starts at the 4:00 mark, but the whole video is useful.
This method worked great for me. And with the bars at a good height, I can ride in the drops as just another hand position, not only for extreme headwinds or steep downhills. It's so nice to switch between drops and hoods on longer rides. My bars are considerably higher than his example bike.
(with my somewhat curved back Fizik saddle, I have the nose slightly up from level. The horizontal part of the saddle is now closer to the back, just right for me. That's very common with Brooks saddles too.)
