Floppy branches are hard to cut with a sawzaw.
Grabbing a bunch in one hand and sawing with the other can work.
I've taken down a 15' tall honeysuckle with just a sawzaw, it works great on stiff woody branches.
Usually a pair of hedge trimmer can easily cut the smaller whippy branches.
i ve a battery sawzall for gardening work. it has a spring loaded claw to grab the flexible branches. it uses normal sawzall blades but has a special blade to cut green wood. it came around 40€, supermarket quality but 3 years warrenty.
The long straight edge on the trimmer will do a nice job. Sawzall won't trim the small ends at all. They work best for dropping small limbs and especially any cuts on brush or shrubs you have to make right at ground level where you don't dare put a chain saw.
