After trying ghetto tubeless and failing i tried to go as light as poss with my tubes and bought some maxxis flyweight. Failed. Way too light weight for me although are handy for a compact 'get me home' if needed.
Good medium weight trail tubes at good prices is what i'm after here. Do share.
I've found Schwalbe to be good. No idea if they're heavy or light though.
When I used tubes, Schwalbe were my favourites too.
I've been using Maxxis Ultralight Tube on my race wheel. Havent got a puncture but only done 2 gorricks on them so not that
There a bit heavier than the super flyweight obviously.
Got them from CRC.
Sound i will do some browsing.
recently switched to the bontrager 2.2-2.5 midweight / all mountain tubes. heavier than regular xc but not monster dh thickness. really pleased and we run them on all of our guide and rental bikes now to keep puncture time down to a minimum.
hope this helps.

Have been using [url= http://www.chainreactioncycles.com/Models.aspx?ModelID=5662 ]Nutrak[/url] tubes for last four years or so and only one pinch flat in that time. Excellent value, though I don't see sensible MTB size on the current CRC stock list.
