So far since the windstorms blowing thourh here I have been doing allot of white pines. I have been in them in the wind probably about 5' from the top not TIP, top, And just to rehash Rap your rope completly around the trunk. Ladder climbing is nice with two lanyards then set your line were you are comfortable and prune down, its the fastest way I found your groundie wont like it much, especailly when all the brush falls in one big clump. But I really dont think they would mind unless your one of those climbers that are just to good for dragging brush.
