Hi there.
I have a 1.5" rockler Dust Right FlexiPort Power Tool Hose which I have hooked up to the 1F dust boot, using a 2.5" adapter. I sort of like this hose because it contracts when not in use, which keeps the hose out of the way of the router.
However, the dust collection seems mediocre.
Would it be better to flip everything, and run true 2.5" hose to the Dust Devil?
