I do this too.. I don't really like EOF, but at least I can do something in Guitar Pro. The only thing I wish I had was a program that could change all the notes of the same pitch to other string, so I could import it from Aria and generate a .gp5 file faster. Trust me, Aria is a top-notch program when it comes to making songs, but it can't export .gp5, just .mid, and this way you can't put any guitar techniques like slides on it, so you need something like TuxGuitar or Guitar Pro to finish the process which makes things slow for me... I'm actually thinking of making a tab editor program myself since I'm a programmer, if anybody has documentation of how the .xml files for Rocksmith work I would be glad to see.
