Hi Nate
I usually work on my pines in spring(selecting new candle growth back to two and thin out older needles then wire) and summer(if tree is healthy, decandle the spring growth, otherwise the same procedure as in spring) and autumn( sort out the second flush of growth, same as in spring ). I cut back hard in the spring and summer because that's when black, red and radiata pines are pushing their first then second flush of growth. And it gives the buds enough time to grow into shoots, which can then be wired to begin building branch structures.
I am not a big advocate to just decandle in summer. I found that if the tree is not vigourus enough, the second flush often don't grow into something that I can use by autumn. So I'd not decandle in summer to let the less vigourus tree gain strength until the following spring, then cut back hard to closer inner buds. Obviously I'd feed the weaker trees well to promote back buding. At this stage, shorter Internotes and needles are NOT the objective, but the nurturing of good viable back budings.
It's a complicated subject. My approach works for me. All my pines are done to promote strong buds so that the customers don't have to.
