I think I struggle to really understand the methods behind it all - Unless there is some significant cost barrier (for the manufacturer), why not make the "best" rubbers available to all?
Surely the increased profit/market dominance would be the goal, rather than producing a small batch for a Pro.
Unless there was certain characteristics in the Pro rubber that didn't translate well to the mass market?
It'll always be a hard one for me to trust, because the reports are all 2nd and 3rd hand accounts of what people think (with no source being particularly specific).
Whilst there may well be subtle differences, I'd love to see and feel just how obvious these differences are in person.
Comparing my forehand loop with D09C and Timo's forehand loop with D09C just isn't a fair comparison...... For Timo! 😂😂
I think you raise very valid questions.
D05 for example, Butterfly said, they made this for highly skilled players, then we have people here saying its okay for amateurs.
You just can't define what is "okay", since you mentioned, everyone's context is different.
Why doesn't CNT players all use the same special edition, and each player have customized to minute figures? ie 41.5 vs 41 degree or 42 vs 42.5 degrees
So, from a business stand point, I think Butterfly made the spec they think is okay for the masses and classify them accordingly to what they feel is appropriate, and the masses are the ones that are "delusional" at times (but this is some other subject to Pro stuff, but closer towards this thread, haha)
Tenergy 05 Hard, I felt was in that direction of what you said.
Pro version became retail spec
