I am using Century Gothic with an overline for heading1. The line is nice and thick. However, if I try Helvetica LT (purchased from Linotype), the overline is much thinner, and a little closer to the top of the characters. Is there any way I can control the line thickness? The Help tells me how to turn it on and off, and that I can't control the element in equations, but I'm hoping there's a trick. ?
