We used team pre-emergent from the mid 1980's through the mid 1990's. After impressive testplot results we elected to use pre-m from 1996 through 2003. For the last 5 seasons we have used dimension and for the most part have been pleased. Just for $hits & giggles we used lebanon/team on several acres of cemetery last season. The results we attained were very impressive in a hot drought season. Bottom line, don't disregard older technology.
