Setting sag is easy and so is moving the forks in the triple clamps. Set the sag once and forget it unless you lose/gain a lot of weight (or plan on packing 25 pounds of mud on the ride, maybe), but the fork height is something I routinely adjust if I don't like the way the bike is steering that day. Takes less than 5 minutes, is free and reversible, and the results are obvious and effective.
Personally, I'd start there before messing with the clickers (especially if it's overdue for service!), unless there was something I didn't like about the straight line whoop performance of the shock (like bottoming, or packing, or bucking you off like a rodeo rider). But once the sag and fork height are right, clicker adjustments are all that stuff too, free, reversible, and instantaneous. I can't believe how many people never touch em.
On the other hand, I think road racing breeds overanalyzation of dirt bike handling, and I'm guilty of it...on pavement, the feedback is so good that you can't help but hone your perception of what the bike is doing...but I know some pretty damn fast woods riders, guys who can win A level motos, who never road raced and literally laugh at me when I talk about sag or fork height...they are the exception, not the rule, and they weigh somewhere close to the average size rider the bikes are being designed for, but they just twist it with seemingly blind faith that what's over that next big pile of rocks is something they can deal with once they find out in mid air that they won't clear it. And most of the time, they can, because bikes land better when they are wide open (LOL)
