Radiata, I found these to be hard as nails for the most part. Learned my lesson on wiring, they're too vigorous at this point almost ring barked them, in future I'll endeavour to secure trunk wire via the soil.
Pretty sure this one's halepensis (up for correction if someone knows better). They're much harder to manage than radiata, they grow quite leggy with strong branching.

These radiata put on some strong growth during winter, particularly over July and August. Not sure where im heading with these, keep 'em short, keep 'em bushy and deal with it when im dealing with it. Same trees/order as the original post. Oooops... might have gone overboard on the bushy (summer '24 seedling @ roughly 8mths).

These things are getting away on me. Will cutting back to a new pair of branches bud back into the needles or will I need to cut back into the needles themselves?

All pines will grow new buds from any healthy needles after pruning but usually only a few of the needle clusters close to the cut. If you want buds in specific location best to cut just above that.

That pine appears to be radiata. It will always bud wherever there are needles. Radiata will often back bud on bare wood so you can cut to the lowest needles and hope for buds even lower.

Halepensis is more like other 2 needles pines so usually only buds from healthy needles.

Yeah radiata. Coolio so back to a pair will be sufficient. I don't want to cut into the needles unless I have to.

Edit: Misread the second paragraph, into the needles it is.
