And is that as deep as it goes?
Ally,
The only non-ego based reason coming to mind is:
Based on personal experience, slower greens tend to be more bumpy, and faster greens less so. There are probably a few exceptions of course, but it could be many courses have sped up greens in large part to make them putt more true.
As to the original question?
Truth
As to Kalen's post above?
Mostly myth.Faster greens are only "truer" when they are pure, and a nightmare when they aren't.
If greens are healing or in poor condition, I'd much prefer they be on the slower side.
Both can be bumpy, but on a slower green the ball can be struck firmly to power thru a bump/imperfection with minimal comeback consequences.
On a fast green, every single imperfection is more relevant because the ball is travelling more slowly, and "powering thru" an imperfection such as aerification, spikemarks etc. can result in going many feet by.
Of course everything is relative, but greens have really gotten faster across the board the last 5 years or so.
Aerified greens that are healing are now often lightning fast whereas back in the day they weren't rolled as tight or even mowed to promote healing.
Fast and bumpy is zero fun and it's common now in competition in the spring.
Watching NCAA Tourney now.
You'd think these kids were terrible putters inside 5 feet.
They're not.
There's evidently little tolerance for slow greens-ever, and consequently even when healing or in poor condition it's demanded they be fast-which further slows the recovery.
People don't like slow greens because they demand solid contact-fast green absolutely do not.
