Paul & Bob,
I think some/many clubs develop cultures based on conditioning.
Certainly, televised PGA Tour, Opens and the Masters have influenced conditioning and speed.
Golf's an interesting game in the sense that other golfers, irrespective of their proficiency want to emulate the best golfers in the world, especially when it comes to playing the "same" course and the "same" conditions as the best players in the world.
There's also a desire to import the conditions they see on TV week in and week out.
There may be an awareness of "critical mass", the point at which conditions become unplayable or unmaintainable.
I think that's what Bob was referencing in his last paragraph.
But, nothing I've come across indicates that there's a reversal in the increased speed trend.
If anything, as Bob indicated, his club was in quest of higher speeds and achieved them by the introduction of Ultra Dwarf
