wp-layout.css suggestion

It seems as if the links on the menu are too close. Maybe I’m just getting old or it could be the browser environment (firebird/moz on linux) but the line-height of the menu* id is low. At least in my case I found that 135% is a better fit instead of the default 115%.
line-height: 135%;

#menu ul ul li {
font-size: 70%;
font-family: 'Lucida Grande', 'Lucida Sans Unicode', Verdana, sans-serif;
font-weight: normal;
font-style: normal;
line-height: 135%;
padding-left: 12px;
letter-spacing: 0;
margin-top: 0;
padding: 0;
border: 0;
}
