Shouldn't have a problem with burning through bowls too quickly. I like to use my vortex bowl, and that always lasts like 2 hours plus for me per pack, which is plenty for me.
And yeah, it sucks when autoseal decides to just not work. Which is the reason I went with the Mya version, the ball is removable so I might do what others keep saying and replacing it with a plastic BB. My Sahara autoseal adapter likes to rust, but the bearing is in there permanently. So as you could guess it likes fail regularly.
