yes I am asking you, because
@vsbabolat made it very clear that prostock is any racket that is not available to the general public but is available to the pro players
and you came up with your silly example of but what if I can still buy a PD 2018 or what if I bought a racket 15 years ago
ok, since you are asking me. The example is purposely silly to illustrate the point.
I'm not involved with any tennis racket brand or manufacturing, so take it for what you think it is worth
1. apparently over time the graphite / resin matrix develops cracks, so the racket that you purchased (theoretically) in 1995, by now should have developed cracks and therefore softened, which means that it will be "flexier", or given all else being equal, it will generate less pace / spin when hitting the ball
That very well may be. Two points though.
My racket purchased in 1995 has never been used so no cracks/softening happened. It therefore is exactly like the one manufacturer made today for a pro.
It's been stated that some pros actually have the rackets strung hundreds of time to soften them before they use them - so if my racket has softened over the years it resembles those pros frames even more.
2. lucky you if you purchased some rackets in 1995 and kept them "pristine". The thing is, I for example can't go to a store, be it brick & mortar or online like TTW and order that frame.
So, when a pro player gets that racket, freshly produced in 2020 or 2021 it is unavailable to the public, but it is available to the pro player.
Isn't this a "pro stock" frame?
It seems you and
@vsbabolat think such racket is a 'pro stock' frame. And that's perfectly cool with me. It just means that if I did have such pristine racket purchased in 1995 I would have had a 'pro stock'. And I would have never thought that since I bought is at a retail store. Since I have quite a few such rackets from the past collected over the years apparently I have quite a collection of 'pro stock' frames.
3. leaving the hyperbole aside.
While today you might still find the Pure Drive in 2018 paint job, in 1 or 2 years down the line you'll probably not be able to find them anymore.
At the same time, a pro player will still have access to the PD 2018. Is it a "pro stock" now?
It seems you and
@vsbabolat think such racket is a 'pro stock' frame. It means that _any racket used by a pro that such pro still gets it via special channels_ becomes a 'pro stock' the moment it goes out of 'regular' production. Since pretty much any racket goes out of production all you need to have a 'pro stock' is to buy a racket used by a pro today, while it is still available, and wait. It also means that there's _nothing special_ about such 'pro stock' as it is literally the exact racket anyone can buy.
4. Now let's take the #3 and develop it a notch further.
A pro player plays with a PD 2018 painted like PD 2020/ 2021.
Say I have seen how this pro player plays, fell in love with the style and want to purchase that frame.
Where can I go today, and purchase that PD 2018 in a PD 2020/ 2021 paintjob?
this is where for me that PD 2018 painted like PD 2020/ 2021 is not available, but it is available for a pro player.
"Pro Stock"?
It seems you and
@vsbabolat think such racket is a 'pro stock' frame. And I can certainly see the point because indeed a mere mortal can't just go to a store and get such racket. Again, it however means that there's _nothing special_ about such 'pro stock' as it is literally the exact racket except for the paint. If you think that paint makes a difference as to how a racket plays - so be it. My argument is less about when you can use the label 'pro stock' and more about whether 'pro stock' has some magic properties not present in 'regular' rackets. You are essentially saying that 'pro stock', at least the types we are discussing here, are 'different paint wise' but exactly the same material, shape, drilling, manufacturing, etc as any retail racket. Which is perfectly cool.
5. Let's take the #4 and develop it a bit.
Say this pro player plays another 10 years with the same PD 2018 painted like PD 2020/ 2021.
If today I could still buy a new PD 2018, in the PD 2018 paintjob, where can I buy a "pristine" PD 2018 10 years down the line?
and where can I buy the PD 2018 10 years down the line in the paintjob that will be used by this player 10 years down the line?
same as above. I see your point. My point is that per this thinking 'pro stock' has no special properties, it is only painted differently. It is no different than saying that a truly retail racket a given low level pro plays with becomes a 'pro stock' because he scratched it certain way. I mean, a pro plays with it, and you can't buy it anywhere scratched that way...........
