I can see where it could have some very good uses ....... Definately a specialty tool , but appears to be a very good tool ... As I,ve never used all these ropes and blocks and riggin in a tree , I would have to work for someone using them to learn the ropes , litterely !!!! As I have my wife be my ground man , The KISS method seems to work best for me ! Plus as I do most of my tree work rurally I don,t have alot of use for it ..... Last monday I took down some Silver Poplars in a friends yard with the winds to 20 mph ..... As they were leaf less there wasn,t too much pull on them from the wind . But I was waveing around pretty good ... They were cats faced pretty good and about 16-18" on the stump ... Biggest problem was I was wearing my Klien's with pole gaffs and that takes alot of the fun out of being able to walk around and up and down the tree , Crushin my nuts was a real problem , as the bark on them is pretty soft ........ I can't find my Buckingham with the tree gaffs since we moved last summer... The tree gaffs for the Kliens should be here today or at least this week ..........My biggest fear , (Unreasonable ) when topping timber is the tree breaking off underneath me ...... Also on conifers , topping in the wind ...
