It is rather heavy for sure, GC.
Comparable to my old 1980s Besson and far heavier than its Eb contemporaries built in recent times.
This heavier weight is exacerbated by no obvious hold points when handling, so I take it very easy when lifting about, and would always have my tuba stand close-by.
I am making further engineering tweaks to ancillaries which is helping.
It blows beautifully.
