I am on the contrary side to mose of the experiences posted. I am 5'11" and switched out 42 captain bars to shallow drop 45s. Very happy with the switch. For me, it was not the added leverage (minimal if you do the math), but the wider bar stance gave me more room on the top of the bars for a good handhold and especially made steering a little slower and less "sensitive" when in the drops. We are casual riders not racers (anymore) so the wider bars well suited our maturing riding style. They did feel funny at first but I got used to them quickly and really love them. I am NOT thinking of going to a wider bar on my single though as it does ride well just as it is.
