I checked that link out and was a little surprised the author of that insanely detailed bit of freewheel info essentially stated that the ACS Crossfire is on the same level as the WI Eno. I have a Crossfire on my bike and while it's not terrible, there's a bit of play before it engages. When you're riding, it feels like it takes a 1/4 turn to engage - realistically it's probably more the equivalent of 5 minutes on a clock, but still... If that's what the extra cost of an ENO gets you, I'm not sure they're worth it. Honestly, I hope I'm misunderstanding this... I hate that pre-engagement play, and have been holding out hope that once I can afford an ENO it'll be a thing of the past.
