@ocnlogan: its after the fact now, but your 11sp Deore rear derailleur will work with the 10sp AdventX cassette and shifter. If you still have the parts kicking around, keep them around as drivetrain spares. I find the AdventX cassette doesn't shift as smoothly as Shimano's cassettes and about equivalent to Sunrace's 11-46t 10sp cassette, but the price was right when AdventX was on clearout and its also a very competitve weight (especially for the money). The Shimano 11sp M6000/7000/8000/9000 generation of rear derailleurs are not officially supposed to work with 10sp, but in mine and many others' experience it works well enough. And while officially only rated for a 46t max cog, it will get to 48t with minimal issues and many have been able to stretch it to 51t depending on your rear derailleur hanger geometry and chain growth on your rear suspension design.
