Thanks, Padraig. Very interesting.

Bryan, Regarding your post 457, I think I'll stick with my own statement of my theory in post 440.
That said, your graph does provide very rough idea of what I am talking about here. According to your rough observations:
-- At around an 80 mph swing speed there doesn't appear to be a distance difference between the Pro V1x and the Balata.
-- At around 103 mph there appears to be about a 7 yards difference.
-- At around 110 mph the difference appears to be about 10 yards difference.
This suggests that the faster swingers, and not slower swingers, have benefited more from the new technology, does it not?
As you know, at least one other source suggests the gap between balata and ProV1x much larger at around 110 mph swing speed. In the experiment conducted by Andrew Ric, his 110 mph swinger hit the the ProV1x about 46 yards longer than the Balata.
www.andrewricegolf.com/tag/tour-balata/Rice didn't test at 80 mph, but it is hard to imagine that a 80 mph golfer would the Pro V1x 46 yards further, isn't it?
None of us have found credible evidence that that was true.
I don't think this is quite accurate. There is ample evidence that fast swingers have benefited, and there is evidence out there that average golfers have not benefited much distance-wise from the new technology. The R&A study, for example, which indicates that average driver distance has only increased 3 yards. And your own observations above.
On the other hand, none of us have found even a hint of evidence that golfers with slow swings have benefited as much from the new technology as golfers with high swing speeds. Have we?

Doug,
Must be something screwy about this test...at least compared to the Trackman ideal measurements Bryan posted on reply #159.
Jim, Those numbers are pretty shocking, but I am not sure that we can just throw them out based on that "ideal" trackman chart.
