Don’t do option 2! Got 2 sets. Had 2 sets replaced under warranty. 1 set after 18 months, one after 6 months use.
I’ve heard good things about Option 1 carbon cranks from people who then had the Next SL and had issues. They said they hadn’t had any issues with the SRAM cranks at all.
I’d stick with Option 3 as it’s working.
I have the Next SLs and a set of Shimano SLX 3x setup as 1x and really struggle to tell what cranks I’m running when I ride. The weight difference really isn’t worth it. It’s 200g.
My Cinch BB however has been excellent, it’s outlasted the crank arms. Now over two years old and still going strong.
Last set came back in February and I’ve done 1000km on them since then, holding up ok. Previous ones went wrong at 1500km though. Pedal inserts came loose.
The other Next SL set that came back from warranty (lasted only 6 months) were upgraded to G4s and they’re still in a box in my garage! I can’t be arsed taking the SLX off the other bike. Will put them back on when I need to next change chains as they do have over a year warranty left.
I wouldn’t buy a RaceFace Next SL crankset again. Turbine, maybe. To keep my BBs and DM rings.
Shimano cranks are a dream to setup. Wish they’d do a DM setup.
The number of times I’ve had to remove cranks and swap BBs since having Next SLs. 🙁
