I had cross (aka interrupter) brakes on my first drop bar bike. For a while, I mostly rode on the tops, like you are. The brakes were a big help with that, I really liked having them. But eventually I got more familiar with the other hand positions ... and that was good. It meant I could do longer rides and be comfortable, because going from the tops to the hoods to the drops meant I could move my back and shoulders during a ride.
