Awesome work Deva!
I dont honestly envy you working on those stabby ,tangley ,stringy macrocarpa's. I grew up around them in New Zealand but the genetic stock seems to be very different down there.The first time I saw long straight trunks on Macrocarpa trees was in San Francisco.All of the ones back home exhibit decurrent form and while they may be massive through the trunk,they dont get very high.They also seem to be gull of old fencing wire and of course a concrete fence post or two.
