Good point, Murph, on the force in the stretch. I think a dynamic factor when the tree is able to move freed up and begin it's fall. Pulling is interesting stuff to learn about.
Right, not contesting your point, Mick. Actually, I hadn't realized that lower is faster, never really thought about it. I can see more buck for your pull with that in mind in certain instances.
I wouldn't want to have a tree cut up and then left to the pull low down in a do or die situation. It's the cut a little and pull a little that lets people get away with the lower attachment. Still, that low attachment I find worrisome. All in all, higher is safer no doubt.
One thing I've been pretty surprised about is how low you can be attached to a pull tree with very observable back lean and it still goes over as hoped for. I know it defies the rules, but watching some trees being pulled and being skeptical, skepticism was unwarranted. That's how some guys...
Seems like a tree like that can be easily done by yourself if you have something down below to attach a block to and then run your pull line back to an attachment point with puller next to where you are cutting. Easy to see how things develop. As Jerry pointed out in his book, when tight...
Any reason to buy a Tirfor puller is a good one. Some on eBay currently, used is ok as they are tough, as long as not appearing much beat up. Rebuilding is a tedious chore, lots of small parts. That Tractel cable is pricey too when new, but without kinks or anything is cool.
