Responding your pre-edit reply: first off, obviously not all years and models of Boxxers are created equal.
Second, I don't claim to know much about them despite doing two oil services myself.
Third, I'm not such a big fan boy that I don't think RS sucks for not making a fork that doesn't require inverting to work properly.
Fourth, the inversion allows oil to move to above where it ends up in time, THAT affects the dampening and AFAIK, is the basis for so many reports of forks without the proper amount. MOST folks DONT measure what they take out or have someone else service it.
Given the inversion issue and relatively difficulty in finding an optimum adjustment, the Boxxer is probably NOT the best fork out there. BUT neither is it junk or incapable of providing literally, world class performance.
And lastly, as I said, if you haven't tried inversion, then as they say, you just don't know.
Believe me, when the RS tech told, me I was thinking this bozo don't know what he's talking about, but the results speak for themselves.
Oh, and for some of us weight weenies, as long as it can be made to work properly, it IS the best fork. I get an extra dose of happy knowing that the $880 I paid, from a reputable bike shop(in Canada) won't buy anything better, I'm sure at $1200-1400 I would be less tolerant too.
