I'd go for same set up as me :0.
Zee Derailuer (£60 - CRC) and shifter (£30 - CRC), feels lovely, very smoove and youve got the shadow plus clutch
. Single up front (Ive got 32T) and ten speed at back (mines HG something 11-36), that really gives me all the gears I need and does away with the hassle/expense of 2x up front. I havnt worked it out but I think that 32T by 11-36T gives a range as big as some 2x front setups.
Ive got Saint cranks, they are a bit of a rip off new, but plenty of cheap second hand ones online, (

I find my 1st/2nd gears get my up most hills, even I cant get up its not the fault of the gearing its me being unfit, I chuck it in 4th/5th for a DH run and doubt whether I'd ever use 9th/10th.
