I don't think tube thickness has a whole lot to do with puncture resistance. Once the thing is through that thick tire, it's going through the tube. I run 19-26 tubes in tires which measure 32mm all the time. Works fine.
It's true that there are faulty tubes out there, but I've seen about as many heavier ones as lighter ones. Usually it's a seam failure.
And I don't like tubes which make it difficult to get the tire on either.
