Why are inner parts of Rev. 2 Gimbals for DC/DS-24II now plastic and not alu?

There are some reports (including mine) for upgrading the DC-24II to Rev. 2 Gimbals, it's great you made them available by the way!

There is now quite some confusion on inner parts of Rev. 2 Gimbals for DC/DS-24II are now plastic and not aluminum any more?
Users are questioning this regarding long-term durability versus aluminium and if it's really an "upgrade" regarding durability and stability.

Could you explain on why you have gone that route and what was the rationale behind?
I think this would prevent further confusion and questions!
