The burning question is....
will you run tubed or tubeless? The ZTR will obviously be a better choice for running tubeless, the 717 would be a better tubed set up. Though the ZTR can be run tubed as well. The width of the 717 only really matters if you intend to run tires wider than 2.1". It's really your choice. Both are good rims that will build strong XC wheels. Yes the 717 can be spoked to a higher tension. But so far that hasn't seemed to be an issue with the ZTR rim. Personally I've been getting away from Mavic rims lately. I don't like their customer service/support here in the States, and there are several manufacturers that build just as good a hoop as Mavic. So for me, I'd go with the ZTR. But that's personal preference.
