DDM,
LOL!!
If ya wanna do that, or at least speed line it, My buddy's Puget Sound Ropes Plasma line would be just the ticket. 1/2 inch size is 31000 lb test, stretch is 0.5%!! kinda pricy at 3.00 a foot or so...., unless ya got a connextshun!!
As a last resort, I might try using a power pruner, or preferably my 21 foot Silky pole saw to top out the branch. Some plywood on the roof would handle the resultant small falling pieces . I'd be tied in to the other side, and up the leaner 8-10 feet or so. Then I could reach almost to the tips with the pole saw. Why guy the tree at all, it doesn't look unsafe? A great idea if warranted, for sure though.
Speed lining looks to be best, if logistics allow it to be gotten high enough.
Great work and graphic stuff, Mike
