Van Dessel sells a version of the moustache bar. Mtn diameter, narrower than the Nitto version. I liked them on my (stolen) superfly.

Had the On-One Mary bars on an IRO ss bike and liked the angle well enough, but a bit wide for my tastes and basically only one hand position.
I use Nitto Moustache bars on my commuter and have always liked them--they work well for me.
Just got a set of Soma Sparrow bars for a beater, and the juries out on them right now, but out of the box, I'm liking them.
I think the bars I'm really waiting for is something like a narrow drop with the drop splayed out at 45 deg or so. Dirt drops like the on-one midge are simply too wide for my preference--cut about 6" out of the middle and they might very well be perfect. Anyone know of bars that fit that description?
