I would call myself a trail rider through & through. XC speed but not afraid to boost a feature if it arises. Sounds like the ridge back may be more suited to your writing style, IMHO. Allows you the versatility to build it up how you want without having to run a wheelset that doesn’t buying 2 sizes or a custom build. Again, I don’t think you can go wrong with either. Pick which one you think is best, build it and ride it…. Not to complicate it, but the ridgeback 27.5 maybe the Goldilocks bike for you
