175mm vs 180mm or 190mm Crank arms

I know there is a mechanical advantage to longer crank arms and I am looking at getting a new crank from Profile (Chrome Moly) and I am interested in opinions of longer crank arms than standard. My bike currently has 175mm and it seems to work well, but would I see enough difference in using the 180mm or 190mm crank arms? What are some of the detriments? I am aware that the 190mm crank arms will place the pedals .56inches closer to the ground when pointing straight down.

Thanks for any (useful) feedback.
