Cabling should only be utilized in the presence of genuine structural faults.
Pruning's always preferable to cabling for perceived weight bearing issues.
Then I can only assume that all of the literature on developing sound structure for northern orchards is complete hogwash. I can certainly see orchards in California, Arkansas and other places that aren't Nebraska not needing much in the way of help... but then, I doubt that those orchards have to deal with their trees having 1" to 2" thick ice on the branches during a blizzard, and for as much as two weeks afterwards.
They might not be growing Keefer Pear trees, either. I'd love to see an effective pruning technique for them, that developed good structure for high production that didn't involve spreaders for codominant stems... and a lot of them... that are within six inches of each other.
One of our residential properties in a small town has fruit trees on it, too. We would rather have trees on it that produced an edible product, than something like a Bradford Pear that looks the same, but has no fruit. I'll try to get out and get some pics from that property in the next couple of days. Because the orchard trees on a property outside of town have more precedence over these trees, we were unable to "cable" the peach trees, or prune the Keefer Pears on that property. Winter slammed us with storms earlier than normal, and we ran out of time.
The peach trees are a disaster, on that property. I will probably have to replace them in spring. The ones I cabled on the orchard, on the other hand, are fine. The "perceived" weight bearing issues were about a half inch of ice on the branches... I could perceive the problem by noting that these branches weren't normally lying on the ground.
I have no doubt that "correct" pruning on a California peach tree might be all that's needed. I also have years of practical experience on peach trees grown in Nebraska that tell me you'll be shoving a hell of a lot of peach tree branches through a chipper if you rely entirely on pruning technique to keep them in production.
