I’m not an expert but my anecdotal take Is that it doesn’t matter.

if they are established and getting everything they need, i Can prune hyrbrid teas at least twice a year and they are completely fine.

I have noticed that the ones I pruned lower to the ground before new growth have better shrub shape so far this spring.

I really don't think it matters. I just don't like to work when it's that cold still outside and I find it quicker to spot where it needs pruning when I can see some growth popping out.

In watch zimmerman/ben-heirloom rose pruning video's, more or less they did bring down the roses to about 1 1/2-2 foot tops. If I did wait until bud break, I don't now if I would have seen buds as low as 2'

I only state this as when I did the pruning, some buds were minorly breaking all -uptop- before doing the pruning and lopping them all down. I don't know if the -lower buds- would break as low or are they more dormant buds that are triggered by lopping off the tops...

Hence, which led to the OP a well. By pruning/kinda thinking all that energy going 4 feet now being refocused back to only 2' ish . I dunno. Just a noob here
