You say you won't use the drops. Don't. With levers only on the tops you will not be able to get to them fast unless you choose to not slow at all with your legs. (Think about it - say someone stops in front of you. Your first instinct will be to slow your legs. But that throws your weight onto your hands which you need to pull up and back to get to your brakes. I used to use that instinct to my advantage. There were 3 Massachusetts rotaries on my commute, all at the bottom of small hills. It was easy to come in with speed and "park" myself close behind a car - the one place in the chaos of the rotary that there would never be another car. When that car's taillight came on, I slowed so quickly with my legs on that reflex that I would be further behind the car before I got to the brakes. In the drops with regular road levers.)

scoho, I have cross lever on one bike. I never find they interfere with any of my hand positions. Granted I no longer race and probably will never be in a position (or fitness) to push another rider up a hill, the one time when you really do want the real estate next to your stem. Also I have those levers right up against the center sleeve of the handlebars as I don't need them if my hands are outboard.
