Well, I wouldn't have drawn an inference quite that detailed from the changes, nor that any changes were made to cater to any change in eras. I imagine it's more likely that, after a break in production - with a possible change in machinery, staff and supply chain - the end product is simply different from other production versions over the years (as they were from each other as well).
And that's not even considering that they may have sped up, fine-tuned or cut corners during the fabrication process. I'd not be at all surprised to discover any of these things given how in-exact racquet manufacturing is.
I played for two hours tonight with the new frame and the thing that strikes me as being different is they feel less dense through the mid-section - despite being new and, in theory, stiffer than my (close to) 20 year old frames.
