Avalanche damper.
It’s the same price as replacing your compression and rebound cartridges, which is what you’ll have to do if you want to get it to the RC2DH standard……and the Avy damper is wayyyy nicer.
The avy damper is a proper moto style open bath damper…..whilst the RS damper by comparison (whilst decent) is a plastic POS. The avy will also need **** all servicing like the old pre 2007 Marz 888’s.
Here’s a review

Tried a mates….twas wonderful, for the same price as upgrading my fork to say…a BOS….I’m buying two cartridges….when one goes kaput….it’ll go back for servicing and I’ll drop the spare cart in.
Avalanche stuff is proper old school but they still produce some of the best dampers available and they’re brilliant when combined with modern light weight fork chassis’ and new school frame geometry….
One of the best kept secrets in the industry IMO
