Has anyone ever consider removing the dip tube from their keg and cutting about a half an inch off the bottom? I am thinking about doing this to avoid sucking up yeast every time the keg is moved a little. It also would help when filling that last glass not to have it get filled with yeast. I know that you would leave about a pint in the bottom, but too many times I have been filling a growler towards the end of the keg and I hit bottom and a bunch of yeast goes squirting into the growler ruining the whole lot. If the dip tube were a little off the bottom then I think it might avoid pulling yeast after the keg is bumped a little and also avoid ruining that last pint.
