Hey Will.
Looks like they're off to a good start. It's always nice to see that first growth of the season :) .
Are you planning to train the uprights as a single row or are you planning to lean them outward into that sort-of-a "V" configuration? I imagine you could get away with the shoots being a bit closer together in the latter config.
I have 4 trees in the ground, so far, that I'm working on growing in a quasi step-over fashion. Have plans to do a bunch more. All contingent on how much time and effort I want to put into it in one season.
Thanks for posting the pics.
