Thanks for posting this, I know exactly what you mean. Segovia is famous for promoting nails into classical guitar playing, and, along with them, a more direct way of plucking, which results, it's true, in less effort and movement of the hand over all, because all motion is carried by the upper side of the fingers. I don't have nails, though, or at least not the amount needed for this time of plucking, so what I do is plucking with a combination of flesh from the top of my fingers and a bit of nail. I would say 70% flesh, 30% nails. This specific type of plucking requires a different movement, I'm almost pressing the strings to the inside of the guitar.
Here's a very detailed video explaining the differences:
If find the video quite interesting and very informative. As I was studying the classical guitar my teacher was definitely an advocate towards the Segovia method and while we worked on pieces by Sor, Tarrega, Carcassi and others I was totally unaware that these composers advocated having no nails on the right hand. As noted in the video unless your nails are trimmed to the flesh there are instances where depending on tonal and dynamic preferences all flesh or some nail as in your case can be applied which makes for a broader scope of tone and dynamics as a result.
Such great tools we have available today truly expediting are ability to hone our skills and broaden our knowledge base.
I learned years ago that Steve Howe from Yes doesn't have nails on his right hand. I believe much like with the left hand finger tips a slight callous builds aiding the fingertip in striking the string.
