I dont get it
Shimano add 2 teeth to the cassette and suddenly its ok to ditch 10 or more teeth at the front?
Yes No Maybe
It entirely depends on you, what you ride and how you ride. Other peoples mileage WILL vary.
One of the key factors in Cadence, the faster you can spin the lower you can get away with the front ring being, if you can't get the high rpm going (and be happy with it) then you need a bigger front ring and will have to grind harder up the hills.
Next where you live? Is it hilly? Most trail centre riding have nice climbs which take the angles out (most means not all) and let you go "middle ring" all the way up. Mountains tend to be designed slightly differently and can get steep fast.
If you find yourself dropping to the low ring a lot 1x anything will probably not work. If you can hack the bigger ring then it's an option.
Back in 09 I got a new (second hand bike) with 1x9 (36f,11-34r) it was a heckler and I rode it for over a year in that config, I was fitter and stronger then not much got the better of me till I moved back to the lakes. That didn't work for me so well 25% hills were an issue.
Long and the short look at your riding and how you are doing and go from there.
Be interesting to see how the Hope ring lasts, I had an E-13 guide ring on my 1x9 setup and it never looked used years down the line and ran as smoothly as day 1 until I bent it.
