FWIW, I use Hetman after being converted from Al Cass. Hetman stays on the valves
longer and comes in different thicknesses, which I have found to be helpful in
different horns. I use light piston oil in my newer horn and Classic piston oil in my
older horns. I also use their Rotary Valve Oil in my Rotary valve tubas.
