Fitaly is faster than MessagEase... at least, I think so. ME has way too /much/ sliding, just for letters, and slides have to be accurate on direction. My Fitaly slide set - which I keep threatening to share with the world - lets me skew 67° off course and still get the right target (but I still sometimes miss...) And that means that I can blaze away in reasonable expectation of accuracy.
(Having said that, I still want to re-open the subject with my boss of obtaining SoundPilot to speak-your-stroke.)
