those are nice. i have had the same trouble with the moustache/bull/drop problem. i am riding drops now but i want a longer extension, a la time trials. but then i feel weird, too far out from the center of the frame. these look they could pull you out a bit, but also give options closer in. let us know if you find them.
seems like you could maybe flip the nitto 'north road' and get somewhere???
