Just wondering if you MTB ladies have any thoughts/experience on the following SRAM 1x11 questions:

1) The Ovoid front chainring (helps with climbing or is it a hype?)
2) 26T vs 28T vs 30T front chainring. Any preferences?
3) Substituting a 44T sprocket on the rear cassette instead of the 42T? Any brand that you recommend?

I have yet to try my "new" used 27.5 wheel bike with the SRAM 1x11 gearing. But, I was just gathering some thoughts on gearing for future reference.
