I am not experienced, but I would think tying them down while the branches were still young would be helpful to prevent bending. To try to fix this condition after-the-fact might be a pain in the neck.

Gosh I sure am a lot of help, aren't I. Wish you luck.

I also have a site that seems to have a prevailing wind.

On my (in-the-ground 1-2 year) open center stone trees, I pulled down the scaffolds in the direction I would like them to grow. This helped me with decision making before pruning as well. Not wanting to do it all at once or risk snapping a potential scaffold, I'll go out every so often and pull them down a little at a time.

I had scaffolds on 2 Methley plums that were gradually growing back over top of the tree. Looked kind of creepy. They are young enough that I can reverse it by pulling them down.

The apples seem to be doing fine by hanging weights glued to clothespins.
