I have a 5m Silky Hayate but have trouble making undercuts and had hoped a powered unit would make that possible.

I was pretty well decided to get the dewalt when I  saw a review stating they couldn't do undercuts because the pole flexed too much.

I've used the Stihl 2 stroke ones before and know what they can do but too many $$ for how often I'd use it whilst I'm already heavily invested in dewalt ecosystem.
