Look at the angle of your wrists. I find that my wrists and hands feel best in positions that have my thumbs forward and pinkies back. I find that hard to do on many straight handlebars. ( One of the another reason I will probably always ride dropped bars.) As I get older, I am finding I need to accentuate the thumbs forward which i do but rotating the drops and brake levers forward and down. Seems to me you could get the same effect riding "mustache" bars. I love using handlebars where I can vary the effect and fine tune it.
