That's what they had us doing to reduce the push back, I totally take on board what you and Pete have said, and on balance I will leave the hinge alone in future. Thanks for the comments.

 

 

Push-back is what you see in the vid: as the top starts to tip over it will push a pole back at first and then somewhat get pushed forward itself as the pole rebounds. You dont get pushback on something short or sturdy because with no flex it cant be pushed back.

Rather it just pulls on the stem a little as the hinge breaks. Severing a hinge at the critical on a rigid tree will diminish the 'pulling' effect. I'd like to believe thats what your trainer was really meaning and you just misunderstood.

I have obviously misunderstood what he was getting at, he didnt really make the distinction between poles with lots of flex and more study stuff. I can see what you mean in the vid with the movement back and then the push forward.

 

Thanks for explaining that.
