I've used North Roads extensively. Basically, you have one hand position, but that's not the whole story. If set up properly, and other fit issues are all good, a set of North Roads can be so comfortable that you only need the one position. I use drops, too, by the way. When riding a bike with drops, the entire system is different, spreading your weight around the three points of the bike. In this, more aggressive posture, there will be a need to move your hands around some.
Not so with NR's. I've done several centuries withthem on a Trek 520 I had. Got lots of looks, but did fine - better than some, who where rubbing their butts and ringing their hands.
If you go with NR's, you'll want a weight bearing saddle, not a skinny. I strongly suggest a Brooks B-67.
