I think the real reason Fox went to a different coating (and made it bright cold to make a visual differential), is the shocking rate of wear on most of their forks stanchions (unless you do an oil & seal service every 15 hours or something ridiculous).
So being an american company, and terrified of the possibility of lawsuit, instead of admitting fault, they have introduced an 'upgrade' to the standard coating pitching it as the answer to all problems.
To begin with I was skeptical, and unless you don';t get the gist of my argument, I still am. However fox have proved that *most* people buy based on how bling and shiny something is rather than a genuine performance advantage, SO, when it comes to buying a new shock or fork (or having a shock/fork serviced) and you have the option to go for the Kashima for a small £££ increase, then I would go for it....
1) It IS an upgrade in terms of wear charactertics, or at least so far I've seen far less (younger than) 1 year old fox forks landing in the shop in a state of buggered'ness due to anodising wearing through
2) THey hold their value better as there is always a higher demand for shiny gold bling stuff than normal stuff.
So yes, damper/model choice I would say is more important for actual use. However Kashima does offer a benefit in terms of wearing better and holding the resale value up.
Also CTD, I sort of get it, however I am an expert knob twiddler and am above having my damping choices made by a pre-tuned damping knob.
