I've had my eye on this one for a long time and never got around to purchasing it.
Laura, I'd try just cutting any scapes off for the first year so all the energy goes into the fans. I know...it's hard to do but probably worth it. Now that I say that out loud...I need to go out and cut a few scapes from some newly purchased DL's that have small fans and really don't need to put energy into scapes.
