I recently made the executive decision to only use inner tubes with unthreaded valves (beyond the dust cap thread).
So many valves are now stupidly threaded all the way down to the rubber, and allow air to escape from the valve/pump washer interface. It irritates the fuck out of me.
I'm now a happy user of Michelin Aircomp Ultralight (Butyl) in 36mm valve, and not bad at around £2.75 each if you shop around (eg. Ribble, ebay seller).
I couldn't be bothered starting a new thread for this particular gem of information.
