i've tried a few different set ups including track drops, flipnchops, and true bullhorns but nothing for me is as comfortable and versatile as road drops with hoods.
never tried moustache bars.... and you couldn't pay me to soil a beautiful track bike with risers (but thats just me- ride what ya like)
(ed-) gadeaux knows the deal
