Fast 1x11 gearing on carbon frame - YFY-BM-01 or WCB-M-062 or other?

[cmh]

My Cat 1 racer wife uses a 36 on her XTR 1x11. I offer this information for no reason other than shameless bragging. She's awesome.

Your wife is an animal.  And I mean that as a compliment. 

I'm thinking of stepping up to a 34T, 36T would be pushing it for me... too weak and too fat.

I wish my wife would race.  She rides, but not on an MTB.   

Thanks - she is amazingly strong. I remember when I was stronger than her. It's quite a while back now.

She did consider stepping it down from the 36 after we did a ride with friends (another crazy-fast lady and her husband, who is more my speed) in a park where it was either climbing or descending and the grades were ridiculous. I was suffering on my 22/36, so her 36/40 was turning out to be a bit steep for even her.
