I think the main difference is in the rim contour. The HII rim is a mix btween an original Helleberg and a Bach cusion. If you look at the rim from the side you'll notice a drastic difference from the inside contour and the outside contour. The cup may be a little shallower from what I remember and the throat a little larger. I remember hearing a story about how the rim contour was copied from Bud Herseth's and exploded to a tuba rim size dimension, however I don't believe that. I do believe however that this was developed in conjunction between Rex Martin and Scott Laskey for when Rex needed to sub in
with the CSO on the York, whichever one he used. Your best bet if your extremely interested in knowing all of the particulars would be to contact Scott Laskey and ask him what the differences may be.
