I have the ABS, so I didn't think that would mesh well with the Smash, plus I can run the ACS at close to zero pressure. Install was easy.
I was thinking of getting the Secus up until I started watching the install video. First, the complicated air filling, then the install was fairly complicated. Not crazy bad, but then they said don't rest the fork ever again on the bottom of the legs where the Secus protrudes...which is basically how we ship a bike in an Evoc case. So that plus that de-filling/filling operation, that's just way too much for me to worry about. Coilz r better.
When I ordered the Avy damper, I purposely left the ABS off, as I was planning on going Smashpot, just so I would not be in the competing ABS realm. Smashpot adjustability is pretty sweet as well. You can feel the Smashpot in the deeper travel as it has a bit greater travel range where it is active, very controlled feel. The Avy ABS on the DH bike definitely has a different feel. With it, it is only noticeable when you get things really wrong. The fork just won't clank, but there is no real feel to the system as its range of operation is much smaller.
I also have a Mattoc which also has ABS that works quite well.
I am a fan.
I was offered an early Secus when the Smashpot was on backorder last summer. Decided to stick with coil - i jus like em - but the Secus was intriguing. Will be interesting to see what the consensus is after a bit of time. Would be cool if you could back to back identical base forks, on identical bikes - one Secus, and the other Smashpot.
