I’ve got a pair of Vengeance
My advice would be – start with 25% sag, HSC & rebound around the middle and LSC fully open. You aren’t going to really know what your HSC is doing until you get some big hits. If you are getting pinged off stuff, add rebound at one click at time, if your forks are packing down on repeated hits, back off the rebound one click at a time.
Getting the balance right between small bump compliance and a divey fork can be a tricky one and often down to personal preference. I tend to like a more supple fork in the initial stroke, so generally leave the LSC backed off. If you aren’t happy with your fork diving, add LSC at one click a time until you are happy (LSC seems very responsive to one or two clicks on X-Fusion forks IME). If it gets to harsh on small bumps, back it off a bit
