Very interesting; this was a great write-up AJ!
I'd love to see you review a Rocky Mountain one-way clutch spider as a comparison. I wrote a bit about it vis-a-vis [**moving freewheels to the crankset**](https://nsmb.com/articles/reinventing-and-moving-freewheel/), but it _could_ be awesome for this application and because the engagement is instant it wouldn't have any of the lag on technical climbs. It wouldn't have the adjustable float, but again that may not matter with instant engagement.
The only barrier is that you need an 83mm BB Race Face crankset to make it work and the clutch-spider itself. They don't list them for sale on the RMB website, but it's absolutely [**a spare part that's available**](https://www.ridewill.it/p/en/rocky-mountain-rmgrfc-spider-clutch-race-face-for-powerplay-models/777500/). And at ~$150 CAD it's a relative bargain if it works for you.
