If you're chasing ultimate performance with no budget limit, you'll actually get much closer to achieving that with a coil fork. Unfortunately no amount of damping technology compensates for the increased stiction of multiple extra sliding seals (especially with twin air chambers - which describes most current air forks) or inherent nonlinearities (which are technically avoidable, but no one ever seems to get it quite right).
Coil forks on the other hand perform better and more consistently (both over a run, and for a longer service interval before noticeable performance deterioration). They also aren't much heavier once they benefit from current chassis optimisations, and the weight increases are much smaller than what you see in rear shocks:
- 40 Float converted to Ti coil (2850g)
- Boxxer Team w/Charger (2890g)
- 380 C2R2 Ti (2750g)

Udi have you tried the new C2R2? I rode the previous year model and it felt ok but it belonged to a friend who is a bit touchy feely about his bike so it was hardly testing.
Also I'm still surprised how well the bos air spring performs. There is some stiction but it is barely noticeable.
This. I am also wondering how it works. It has a positive and negative airchamber but works with high psi numbers. I ride with 190psi, 20% SAG, 90kg riding weight.
I am still really pleased with my BOS Idylle RaRe.
theoretically, it should have stiction but seems the guy knows ways around it. Must it be secret lube?
Seriously, I had trouble with unbalanced airchambers, tried everything. Then I put a zip tie inside between stanchion and seal and voila, it worked. Phew!
No experience with the Ohlins dampers, but I have four or five days of hard riding on the new Idylle FCV mounted to my Jedi. (I have been on Idylle RaRe's the past two years.) The FCV has an increased hydro bumpstop at the end of travel. (This was coming in handy as I was WAY over shooting a few of the jumps we were riding last weekend.) The FVC is incredibly sensitive over small bump chatter, has proper support to keep the fork high in it's travel and is noticeably stiffer than the old platform.
