Actually it sounds like his family is Balearic. If so this might explain some things about his slinging and his webpage. Yes the Balearics are very famous for thier slinging both in antiquity and in the modern times. They are also a "Culture" apart form thier Iberian neighbors.
In short a very intresting webpage and one that is now saved on my harddrive.

Load it lenghtwise and the odds of it spinning on the right axis on release are pretty slim. Also you get the best grip by seating the missile horizontal.
There's some interesting info on there - he's a trifle limited in his style - but I suspect that a lot of people who were taught to sling by parents have the same trouble. While those of us who had no teacher tend to chop and change a lot more.
