i'm interested in these threads, but do you have data to support statements like flood and drain is better than cf?

i'd like to see data that would support your point of view,,not trying to cause trouble or anything, but i've seen "advise" posted with nothing to back it up.. and i've seen other systems that are in conflict with your statments..

regarding gb depth, how did you arrive at that number?

are you selling ap products/services? (sorry, but i've been "invited" to several presentations about ap, and while they may have some good info, they have no data to backup statements!)
