I'm also running the Zee 1x10 setup (after a ton of trial and error with the RD getting the tension right!) and, like you, have had no problems with the ratio. I'm running 34-11 on the back and 34 on the front and have yet to use the big sprocket for anything but lazy peddling through grass, I think. As you say, though, not the biggest hills around here but I imagine if the going gets tough you just need to get your bum out the seat. I start to spin out a little on some downhill sections, though, which makes me think a 36 up front could be more suitable. I can't say enough good things about that RaceFace NW chainring. Between the three people I know who are running one, not a single chain drop through Enduros, jumps and heavy bails.
