I suspect most of the really crappy tree owners (crappy trees not crappy owners) don't frequent the forums so the opinion here is going to be slanted toward those who do there own research and have trees that are reasonably accurate. The last junk tree owner that posted in the forum got blasted so even if they're around they're keeping quiet. lol
Another downside to the OP's suggestion is it would require anyone who cared about the system to spend time looking at other trees. I'll pass.
