"The fin adjusts quicker than the skier"

[Gloersen]

...while at the end of the lake after the opening pass following a favorable fin adjustment, yet contemplating another and whether it could be made even better; the thread title's wise words were spoken by @JackQ.

 

If a tuning change leads to improvement, might be best to stick with it for awhile; perfection is the enemy of good.

 

2nd set was even better with a skier adjustment.
