I'm posting this to come back to the original question. I'm playing this lick (I don't quite master it yet) where I tap with a thimble on my right hand ring finger. The last high note is on the 36th virtual fret.

If you wonder how I came up with the technique, I didn't, it's the opening lick for 'guitars suck' Ron thal's tune...
