From reillyranch:
" When the ashes fall into the bowl and allowed to sit on the cleaning system, it absorbs mositure from the air and drippings. It turns into a sloppy clay mixture, keeping your cleaning system bathing in a corrosive (fatty acids and salty marinates) wet mixture until you clean it out. "
From AJ:
"In using either set up, I recommend that you put a small amount of grease on the handle where it slides into the connection, or for those hwo know, "Anti Sieze" And if you go with the "Hex" set up, change the screw to SS. If you ever need to remove them, spray some WD-40 or a really good penetrating oil. Then leave ti alone for a few days. Repeat it. "

"Can't speak to its longevity, obviously, but I like the way the sweep handle stays locked into position instead of twisting all around like the thumbscrew type."
All these things make a lot of sense.....
I'm still not completely sold on the "H" type, as they use the bottom of the kettle directly as a pressure point, just doesn't seem right.....
Maybe I'm just old & set in my ways......
