The methodology I use to set damping has progressed from originally a pretty much 'trial and error' method to one that sort of make technical sense (at least to me). The problem with a triple clicker is which dial to adjust????
As rebound is the most important and also affects compression it needs to be set pretty close to correct first. So what I do is initially back both low and high compression damping way out to largely eliminate them from the equation so as to focus on the most important rebound damping.
While the 'bounce test' may serve as a starting point for setting rebound, that about all its good for. A slow rebound may initially feel good as it makes a bike feel really stable in a straight line, BUT that comes at the cost of being harder to turn. It takes more muscle to push a bike into a corner when rebound is excessively slow. Think of it as the suspension having 'arthritis' in the suspension, resisting the small movements that allow the bike to float into the corner. What I'm looking for is the slowest rebound setting that doesn't affect cornering effort. I'll increase or decrease rebound speed till I find that point. If loosing it makes the bike turn easier, I'll keep coming out one click at a time till it doesn't make a difference. That's my rebound setting. That will generally be a quite quick rebound.
Next I take slow speed compression up till I get exactly the same result. Excessive slow speed compression just like excessive rebound will make the bike feel real stable in a straight line, at the cost of turning effort for exactly the same reasons. So I increase it one click at a time till I find that point where again greater effort is required to make the bike turn, then back it off one turn. Slow speed damping basically set.
Then finally high speed damping. On the road I reckon that's the easiest one. Just increase/decrease to find the point that the 'bang' (technical term) when you hit a big square edged pothole is tolerable. For the track this setting can be tightened up as there won't be those potholes.
Record the above settings, and from there experimentation a bit if you want, you can always go back. Just remember when counting clicks to always count 'zero' as the first click out from fully seated to return to your original setting. If you count say 9 clicks in till fully seated, and then 9 clicks out using 1 as the first click out you will end up at a different setting (one less) to what you started. Try it with pencil marks on a piece of paper to see why.
