Music notation and then tab or both, is the most precise way for me.. but I am old school .

I checked out your site it is pretty cool , the ideal situation would be to have multi media tools (audio and video) plus music and tab .. all of it and the audio/video shown be real easy to run in several slow motion speeds with the notes staying in tune... I know this can be done because I do this myself with some audio video in DP and cubase.
