It worked well with the semi-sweet cooker (variety not known):
Weighed down by fruit, the “super stooper” lowest branches were worth removing wholesale,
and it was easy to spot bad areas of light-stealing and crowding
(which leads to on-tree fruit damage through jostling when the wind blows).
Warning: it felt odd making the first cuts, but I immediately saw the benefit –
something you have to visualise in winter with bare trees!
