If you really need to run such low pressure, "Tubliss" is probably better for you - supposedly you can run all the way down to 0, though I've never used it.

the Tubeliss system gets great reviews from the guys running it. Only downside for it is that it's pretty expensive, and adds a lot of weight. More weight than a tube.
