hi, on the pine on the left, the wires enter inside the bark, so for me it is time to remove wire (and put a new one).
IMO you need to have a clear project on your pines in order to decide what to do... for example, if you want a small and ramified JBP, you can remove the strong candles in the end of June ( mekiri) and wait a few weeks to get new shoots. if you want the pine to have bigger trunk and size, you just trim the long candles in the middle (naka-mekiri) and let the tree grow this way year after year. You can leave some sacrifice branches to thicken the trunk etc etc
As soon as you know what you want for the future, you can decide (with logic) what to do.. or people here can help you to reach your project (with logic)
