Hey Jay, good to see you.
Yeah, from what I know the only change is lengthening the tube a mm or two so that all DTs will fit. Besides the Rubber Whistle tip, that comes on them, with the older shortest Mini, I had, out of a bunch of 801 DTs, only one that was short enough below the o-ring that did not though the mesh. And I have no idea where it came from.
Worst case scenario, like I have some of the original, shortest ones, I am willing to pull out the dremel to shave a bit off of the DTs if needed. I'm not going to do that unless necessary.
Hugs to you and SO girlie, Alice
