I agree with your description pretty much. I also have a rook and there isn’t much difference.
That is the one thing I don’t like about most Ti body/ other metal rings> they don’t have that Ti/ring/sing/thing. The rings seem to be very effective sound deadeners. My one caveat.
I really enjoy my singing Ti yoyos.
My best singer is the Luftverk 000. Beautiful ‘noise’.
I like the 000 play/sound/shape/weight/diameter /recipe so much, I have four 000 yoyos.
The RSO Ti Bowl also shares the same hollow bell shape and it’s also a pretty good singer🤓
