Our hedge is far taller but what we just had done was we paid an arborist company to reduce it several feet to a height I am happy I can maintain using pole-trimmers and ladders.
The equivalent Stihl Pole-saw would be the HTA86 and it extends to more like 4m giving a working height of about 5m, so around 1m more than the hedge trimmer. I have the 85 models of both and they are great (until you get the saw blade stuck in a branch 4m up!)
I use the AP200 battery in both of these and also my Stihl electric chainsaw. I find for the hedge trimmer, the battery has far more life than my shoulders do. It really can do a lot of work, so I'm glad I didn't bother with the AP300.
I'm not sure I'd want to use it to reduce a hedge though, you end up doing nasty spear cuts. You might have a lot of stuff to get rid of after too so I'd be tempted to pay someone if it's a 1-time job.
