Lastest bike is 2x10; the 10 speed XT is circa 60g heavier than 9 speed so there is weight saving there as well as with the shifter. I am looking to go from 42/28 11-36(10) to 39/26 11-34(9) so running 2x9. My riding style means (I think) I can do with less gears - I ride on 3x9 and can deal with the cassette gear spacing; the really important gears being the small ones for climbing. I am hardly ever in the big chainring off road so losing the high gears is not a problem, on road I would just have to pedal faster
Trying to gauge opinions as to how that will work out - anyone tired 2x9 combination? ..... looking around a lot of people have gone 1x10 or even 1x9 so I can't see any reason why not to try it, unless there is something obvious I am missing?
To be honest I do not see any incentive to switch to 2x10. The terrain I ride is quite steep, that is why low gears are essential for me.
I do not think you will be missing something from switching to 2x9. The main problem I see is that sooner or later high end 9 speed cassettes are going to be hard to find...
As for 2x10 to 2x9, only you know which gears you currently use, so what to go to depends on that so you can cover your existing ratios usage.

I've just replaced the chain, and cassette with an 11-32 9sp. I know it's the wrong time of year to be replacing drive train, but both chain and cassette were shot. Incidentally, the chain I'm using is a 10sp Shimano which I received by mistake. I couldn't be bothered to send it back and wait for the correct chain to show up so I thought I'd try it with the new SRAM 9sp cassette. It works perfectly, so you can use 10sp chains with 9sp cassettes after all.
So if you team the right size chain ring with the right cassette with enough range for your riding style and terrain (be it 9 or 10sp), then surely that's the better and lighter option in the long run compared to a 2x9 or 2x10 set up? That's what I've found anyway.

I have been running this 2x9 setup for the past 3 seasons and it has been flawless.
Works phenomenally. I like the 2 chainring deal and was running it before XX came out. Given that even with 11-32 in the rear I rarely use the 26, I saw no reason to drop $$ on 2*10 for the extra gear. Planning on burning out my remaining XO cassettes and then getting XX1.
Really love the 9 speed sram stuff. more reliable than their 10 speed.

i tried one of my local hills and to my surprise was able get up it but was on the largest sprocket (34T). but as I like to use the smallest but one so I always have 1 smaller gear in reserve, i will be looking to swap front to 39/26.
haven't got used to the two rings on the front - on a 3x9 i am mostly in the middle ring except for steep hills, with 2 rings i am not sure which i should be in - there seems to be an overlap between the 2 rings so I can be in either of the fornt ones but with different sprocket.
a 39T would be close to middle ring gears.
as an aside, had nasty case of chain suck where the chain managed to get past the chainstay - took about 10 mins of bending and pushing on a KMC split link to open it else it would have been a 3 mile walk home - luckily no damage to the carbon chainstay.
middleburn duo with XTR M970 front shifter, M970 front derailleur... used the limit screws to stop it from overshifting...
Then I upgraded to XTR M985 left side shifter and M985 front derailleur... shifted way better.
I run a 11-34 rear cassette.
The middleburn has since been replaced as the ISIS bottom bracket kept failing. I now have M985 28/40T front crank.
