I haven't owned lyrics for a few years and not ridden these yet, so I'm unable to offer a solid answer yet. However I'll likely just set them up like a do all my other forks, (in the words of my friends) "stiff". I just pump air in til they feel stiff enough for my riding style and size. There is a guide on the leg that helps. Add enough clicks of rebound to not top out and away we go. Lucky I'm a really smooth rider...
The last lyrics rode really well. Travel is plush, legs are stiff, adjustments all work nicely, forks can go a reasonable amount of riding without a service. They are an all round winner.
Weighed them and they were 1.9kg, giving me a 900g saving with the change over.
