I use dust collection hose from rockler. It's bigger, 4" I think, and corrugated, but it's clear, so I can easily see what's happening in there. I use a shop vac detail attachment so I get strong suction to pull them off the comb, but the velocity drops quickly inside the hose, and even gentler into the box. It does clog sometimes, but I can see it, and a few taps, or blocking the relief valve clears it up. I get very few dead bees in the box. Downside, the large diameter makes it kind of a clunky, heavy pain, but its very flexible, and works well enough that I haven't changed it out for anything else.
Mistakes are the best taechers
