I want to add here that the younger one is better investment as the ages where the fast trainers have the same gaining, is 18-21. After that they dropping. So start with the 19 y.o. your tests. Also from my experience, left-right-either foot doesn`t matter for being a succesfull (or not) specialist.
I concur, and would add ONLY train SA to a 18-19 years old fast trainer.
