Justreviving this post as I'm also interested in the subject.
To bring up a previously asked question:
Does anyone do their trunk chops as Rlominski mentioned and leave a branch below the chop
It seems reasonable to me that this would be a good idea in the sense that it may give a better branch porportion(thickness) from top to bottom.
What I'm saying is the branches left behind by the chop will always be thicker than the new growth above it. As the new leader grows from the first chop the left over (bottom) branch fattens up also. The next chop may leave behind a branch half the size of the lower branch and so forth, getting thinner towards the top. Like I said before they should always stay in porportion to one another this way... wont they?
Is this what Colin Lewis is getting at? Or does everyone just deal with branching later
