I've just come front a 2x10 system and I was a firm believer in it as I like the bailout confidence the front ring gives me. Having used the 1x12 system, it works very well but you find yourself really having to shift quickly in tricky spots and that makes all sorts of clunky sounds that can't be good.
If you're only looking to drop weight then go 1x11, otherwise 2x11 is nice and safe.
Let's see some pics of your bike.

Hahaa yeah it never occured to me I could post bike stuff here also! I will post later :D Yeah I propably will keep the 2x11 since it's free and 1x11 would add cost. (btw followed you for more bike content)
