It seems to me that standover is a poor criterion for sizing a frame. Top tube length, as Sheldon Brown recognized, is much more important, and for me, getting the bars to a height that I'm comfortable with, and doesn't have 22 cm of stem out of the head tube, is also key. With threaded stems, this is only possible by using a taller frame than people want to sell you nowadays. With threadless, OK, but you've got to get to the bike before someone's cut the steerer down.

One of my rides is one where there's no way I clear the top bar if straddling the bike upright -- the answer is “don't stand the bike upright” and I'm perfectly comfortable on it. I don't feel like I'm fighting the bike at all. I like older English frames because they tend to have shorter top tubes, even when the height of the frame is taller: bike referred to is 63 x 57. French and Italians preferred a longer top tube, in general, with Japanese and Americans somewhere in between, depending on who they were copying. For someone high-waisted/long-legged/normal-armed, that means looking for stems with really short extension, which is easier said than done, in the used bike marketplace.
