One technique bogging me down at the moment is "rasguedo abanico". Now, I'm not asking you how to do it... but how long it takes to get over the awkwardness of the technique itself. It feels unnatural to me, hence my question.

The unnatural part being ring and index... middle and index I'm ok with, just not at a blistering pace I saw these mofo's do it on youtube. But it still feels awkward Does it ever leave the awkward phase?
