Exactly...put 3 tanks through my 461 on a maple this morning and these outerwears are pretty impressive to me. The fines just collected on the outside of the prefilter loosely and fall right off like you said clem....
I wanted to run the 046 a good amount this weekend but the stud on the bar adjuster broke 1/2 a tank in, but it was running great at that point. Ran the new to me 066 for a couple tanks and the outerwears looked good on that saw.
