I would say that is true for many producers. If they are large enough to justify a pump, they tend to go that route. I feel it was over-recommended at the beginning by equipment companies. It should have never been recommended or used in flat or low slope installations. A good number who put 3/16" in their woods and then pulled it out and replaced it with 5/16" and a pump. It mainly has caught on with smaller producers who can't justify a pump, those with really good slope, and those who have figured out good sanitation methods that work for them. It does and will continue to have its place in the maple world.

Unfortunately it takes a while for research to catch up to practice sometimes. Hard to study sanitation in 3/16" tubing until it was out there for 2-4 yrs.
