I recently replaced my DPX2 with that Mara Pro partly out of experimentation and partly out of the fact my DPX2 whistled at me all the time. Overall it's a better shock. Slightly heavier than the DPX2, but it has more adjustments and is a very smooth in comparison. I like the 2 platform switch. Rarely did I ever find a need for the 3rd setting on a DPX2. I can tell the flexible piston on small chatter. Manitou Mezzer paired up with this makes for a VERY comfortable ride on general trail riding. No comparison to the Fox 36 and DPX2 combo. Whether in the bike park or pushing through choppy stuff at speed, the Manitou set up is superior.
Only suggestion....make an optional remote for the shock. Would be nice to be able to keep hands on the bars and eyes on the trail. I feel the vast majority of trails are more rolling climbs and tech descents vs long sustained climbs and DH. Having quick access saves time in races and increases fun in general riding.
Thanks to all the people Hayes who go out of their way to please customers. I will definitely be back, not only for their quality products, but their exceptionally great service!
