For me, the real test of comfort is what works on a 100+mi ride. If I'm riding 8 or 12 hrs in a day, its going to be on drop bars. It has nothing to do with wanting to be like a racer or any of that. There's no room for nonsense like that on a long day on the road. For short rides, where comfort doesn't really matter much, you can use whatever bars you want.

As for the Brooks, I think it will depend on your saddle to bar drop. If they are at fairly equal heights, it might work. If you like your bars lower, I expect it will be a problem. I have a swift on one of my bikes and I'm glad its the one with the bars at the higher position. If I stay in the drops for a while, I can feel it.
