Not just Nittos, but bullhorns of any kind on a city track bike makes sense. Considering a big part of skidding and standing is being forward over the front wheel, bullhorn bars allow for that.
I like them for accerleration too. They're stiff as can be, and very comfortable throughout the day. They offer a few hand positions too. If it helps any, I'm riding Profile airwings, and I'd suggest them to anyone.
