Longer version...
I know gig bags as well as anyone else, but I've never shopped for one quite so large. I did have a Gotz for the PT-7 and for the Willson 3050RZ -- both large tubas, but still not as large as the Rudy. So, I'm not quite sure what I want to do here.
Gotz -- love the design, love the style. Harder to lift the Rudy in and out. For such a huge tuba, a svelte bag would be helpful.
Superfine -- Only interested in the clamshell, and would LOVE to get one in leather. But for a 26 pound tuba, a leather bag is going to be weight on top of weight, and that scares me for the long-term/old guy stuff. And long-term, to me, is the whole point of buying a leather bag to begin with.
Cronkhite -- knockoff Superfine, I'm good.

Kariso case -- I'll be real -- if I had an SUV or van or something large enough, I'd buy one of these coffin style cases and deal with the weight for the protection. I'm super nervous that my kids -- being normal kids and running and playing in the house uncarefully -- are gonna trip and fall on my tuba, no matter how careful I am. Seems like an overkill to keep the tuba in a case at home and use a bag for getting around town... but it's an (expensive) option.
Anyway, Alteiri has got to go, so I need to decide the new thing soon...
