as a product manager, I use 2 tools for wireframes and flow design Flairbuilder and OmniGraffle http://flairbuilder.com/ http://flairbuilder.com/ http://http://www.omnigroup.com/products/omnigraffle/ http://http://www.omnigroup.com/products/omnigraffle/ The Flairbuilder developer is quite active and responsive about updates. I switched here from Balsamic because Flairbuilder allows for somewhat dynamic & functional mockups. http://twitter.com/#!/flairbuilder http://twitter.com/#!/flairbuilder
