"Focusing the energy" is, I think, used to promote cone production. From what I understand, the primary focus of growing 1st year hops is root development, best facilitated by keeping the vast majority of, if not all bines (so based on a good deal of reading, popular opinion would be to go with option 3).
That being said, as an igonorant noob last year I pruned bines, got a decent harvest, and still had gigantic Medusaesque crowns this spring. These plants are absurdly hearty.
My 2- year-old newports also stalled out in April, but have bounced back in a major way following 10 days of better temps. I would advise being patient and observing whether growth recommences and if these new shoots appear somehow superior to the first round of shoots. Even if they do, I do not believe I would cut the existing bines.
