Looks great! Regarding vigor, I found a 2005 Cornell bulletin on growing currants and gooseberries. In it, they describe how they found that it’s really helpful to have high N levels during establishment for red currant, even if a soil test shows it to be adequate:
Red currant plants (one year old) started out the season green and vigorous, but after about a month of growing began to show yellowing and a lack of vigor. Fifty pounds of actual nitrogen per acre were applied (injected through the irrigation system) in May of two consecutive years, When no significant change in vigor or yellowing occurred, this was followed up with two additional 50 pound applications, one in June and one in July. The plants greened up and put on 1-2 feet of nicely branched, new shoot growth. No branching occurred in the first year. The approach for the first year was to be conservative with fertilizer applications because a soil test on the site showed that nutrients were plentiful. If the plants were to be grown as bushes for mechanical harvesting, this approach might have been useful as a way to check excess plant vigor. Mistakenly, it was thought that restricting growth to a few branches would invigorate them sufficiently. But this was not the case. In a consultation with Adri Van Eck, he stressed that a heavy fertilization program in the first years when plants are established is important. It is also important not to set fruit during the first one to two growing seasons as the plants become established.
It doesn’t sound like you have yellowing issues, but I do find it interesting.
