I realise you are responding to Babolat Official but do you mean players are choosing older model racquets that are softer??
I know there seems to be a bit of fear of stiffer frames in correlation with arm injuries/added vibration etc, particularly on off centre hits.
I think it may be a lot of factors leading to arm problems: / incorrect strings ,
and/or stringing,incorrect technique, overuse (overplaying), players physiology(propensity to back & arm injuries).
Working with juniors playing every day it is sometimes difficult to stop them playing & realise they need to listen to their body & know when to rest.
Some adult players need to be restrained & retrained as well.
On a positive note, if Babolat are going to market a softer, more flexible line then this will address the needs of players looking for this feel.
That can only be applauded.
