Jooo, apologies: I agree "botch-job" is too strong a word for it. I think "uncharted territory" might have been a better way of phrasing it. We're both interested in finding the best balance of cost/performance/weight, and there's a lot of factors. I agree the Cannondale arms are over-priced, but weight-wise they're good, and the system is well-used even on BSA. S-works definitely seem like a great setup if you have one of the frame BBs you listed. I believe the RaceFace NextSL will retail for $500 so those aren't too terrible cost-wise compared to others (much better than Cannondale), and are a lot lighter than I believe Sram BB30 would be (Sram BB30 only seem to save 50g or so over their GXP alternative... which if so means they still aren't very competitive in terms of weight), and setting them up with proper chainline, etc will be straightforward.

I guess a big question for me is whether the Force arms might be lighter than eg XX1 arms. If so that might make them a more attractive weight and warrant the effort in getting them to work. But it seems odd that it would work on many frames: road Q-factors are often 15-25mm less than mtb ones (eg 140 vs 165) , in which case I would think the arms wouldn't clear the majority of MTB chainstays...

Question is, why are the Sram mountain cranks so heavy compared to their road ones? From this thread it seems like the Red crank arms in BB30 only weigh 370g, whereas the XX1 in this configuration (BB30 with spider) is 496g... That's a huge difference!
