From what I’ve read on ‘Ping Sunday’ many Chinese coaches will give youngsters an all wood all round, possible all + blade as a starting blade. To ‘feel’ the strokes. Learn to spin 1st, as this gives control, speed comes with improving technique (brushing) and physique becoming stronger.
Movement drills , really build the right footwork and weight transfer early on which is the basis of the techniques and this is what produces the power, So when at a young age, they are able to produce strong fast high spin balls with what we would consider a slowish blade / set up.
Rubbers are upgraded first , and only when the coaches says so.
blade is a later upgrade and again only when the coach advises. Possibly to Off- or Off.
This is what I’ve read, so no experience of this personally, so if there’s anyone out there that has been brought up through the Chinese coaching system from junior onwards it would be great to actually hear from you and get some 1st hand feedback!!!
Once at the highest level I guess they choose what they want (but still take advice from the coaches)!!!
