I don't know anything about those brake levers, but is there any way to modify/adjust the travel on them? Seems like there are shims you can add to *some* levers that allow them to "start" closer to the closed position, which may help you get more leverage on them. I've got little hands too, so when setting up drop bars, I have to be careful that I can still reach the brake levers when in the drops.
