Isn't it that everyone of us comes to a point where he has to admit that he will never manage to learn this or that technique? Most of the time it's due to a lack of time or simply because one doesn't get it.

I always dreamed of being able to play tapped arpeggios and scales, fast and accurate without fret noise, creating long fluent runs including tapped passages. I never managed to come further than the usual super simple tappings. I tried hard and almost managed the entire passage of Extreme's "Get The Funk Out" solo, but altghough having a good knowledge of theorie itself, I never managed to come up with cool tapped runs. My brain was blocking in some way.

What's your "I never made it" technique that you really wished you could play?
