I have read and watched on YouTube that I should leave a branch grow for as long as possible to get the maximum growth. See the branch on the right.

From my limited experience growing maples I have found the I get more growth if I let the initial branch grow a bit then cut. This produces a new twin set of branches. Thus doubling the amount of leaves thus doubling the quantity of energy created. I understand that when I cut the branch that the growth is stunted slightly but I feel this far out ways the growth created by the twin branches or oven quadruple branches if you cut again.

The main goal is to increase the size of branch 'A' by letting branches 'B' grow.
Let me know what you have experienced on your trees.
