Tomas,
Thank you, I greatly appreciate your compliment. Also, I see now what you mean with traditional hand position, and I think you raise a very important point. When I learned to play initially, I wondered: How can I sit reasonably comfortable (that is not in pain from wrist or shoulder strain),

not having to pick up my guitar from the floor approximately every 2 min

and still focus on actually doing something vaguely reminiscent of music.

I very quickly learned that my anatomic proportions (considerably taller than Sabicas, with extra long arms) were utterly incompatible with the traditional flamenco posture of holding the guitar with your right upper arm, because I would have needed to bend my wrist well beyond the crack point to get my fingers on the strings behind the sound hole. With the Paco position (crossed legs) I can balance the weight of the guitar, rest my arm on the guitar and play arpeggios, tremolos, and thumb techniques without straining my wrist (although hip and groin is another problem). However, it took me quite some time to understand that for certain techniques (some rasguedos and especially vertical picados) I needed to adjust. For example, I always struggled with my picado on the bass strings. First seeing a video of Paco was a revelation.

(As you know of course) he lifts his arm to create a straight line from elbow to fingers and smoothly moves his arm up while moving his fingers from treble to bass, fixing the angle of his fingers to the strings by leaning his thumb against the wood. I am certain these high-precision robotics are part of the secret to his control, speed and sound. Trying to imitate this technique in my dilettante ways (and if I don't forget) improved my picado and relieved me of any wrist pain.
