Yup, I've had that problem as well with Spocalc. I also ran into another issue building a wheelset with a pair of high flange Campy Tip hubs: seems that 14/15/14g spokes and the relatively thick flanges of those hubs weren't compatible. In other words, the 14g curved end of the spoke couldn't quite make it around that flange cleanly (if that makes sense at all). Seems I need to use 15g spokes with those hubs or is there something else going on?
