What about a new thread just for the DB100-110 results.

lassig, if possible I would recommend testing both before buying....because they both may not work. I have no personal experience with DB200 but I do with bentonite. I would request a sample of each and conduct some experiments with your own soil. See which works best. Also, all bentonite is not created equal. From what I've seen, there is no comparison to the true Wyoming bentonite.
