1. >60 cycles in the past 12 months, about 20 on CX.
2. About 30 on QF, the rest spread across OW partners except a couple of short hops on regional carriers.
3. 1.78m (I only use SI units

Just finished the CX status run (Mini TR to come) and only scored one of the shell Y seats on a positioning flight. Have been in one previously on a medium haul flight.
They're not great - there are better Y seats, even on CX. I would say that they are otherwise very well featured, and the only real issue is your position on the recline. Sliding forward is not ideal, and would be even more difficult on long haul. They can certainly improve lumbar support in their current set up as well. But all Y seats have their limitations on long haul flights, and there's also quite a lot to be said for not having someone else recline into your space. That compensates substantially for the personal recline issues.
Even in CX Old regional J we had some shocking recliners - some who were fully reclined before we had even boarded, making getting seated organized very difficult (in J!); others who reclined the second the gear was off the tarmac. For both safety and comfort, I would have taken a hard shell seat in such circumstances.
If all flyers were reasonable and considerate, the shell seats would lose a major advantage - but since they're not, there's a pretty significant reason for liking them.
