Font Squirrel 22 December 2009 @David- The FF Tisa Pro fonts and all the other FF fonts on Typekit are hinted specifically for ClearType. All hinting should be targeted for that IMO since Vista and Win 7 have it turned on by default. Not only that, but IE itself has ClearType on by default even if it is off in the OS. The FF fonts are actually the best looking fonts on Typekit right now… with ClearType on. But, if you turn it off, their fonts melt into a jumbled pixel mess. Such is life on Windows.
