Not 29er but my Magura Durins were much stiffer than the SIDs that I replaced them with, even though they were QR and non-taper.
The 29er are not that light and very expensive
From looking around I think the SiDs will be the way to go.
Out of interest, how do you go about setting them up?
I may be mistaken but I don’t think these forks use bottomless tokens. Adjust air pressure, then rebound and dial in some LSC if needed. I didn’t use the three position feature but appreciated the LSC adjust that most other models don’t have.
Being completely honest, the “best” XC fork for me is anything built around the Shift Up cartridges. If you can find a structurally fine SID in need of a damper than it could be affordable too. Otherwise it is an expensive way around, but worth it 😀
