I have been mulling this for a while, and I think I hqve concluded that the keif catcher just adds unnecessary work.

Mixing keif into normal doses has always been better for me, compared to a straight keif bowl. As such, i have little interest in seperating it from the rest of the flower anymore. I get better results just having it a part of the mix.

So imo, keif catching is a sub par practice that results in degraded results.

Edit- keif / kief
