I remember this being discussed a lot when the Bulldog came onto the private register (along with a lot of FI chat) .I have never heard of an issue with a CC failing.
I always imagined if the plastic bit at the top 'failed' there would still be enough of the metal CC left to be able to land. I often wondered how hard it would be to reach across to use the P2 CC to land.
Can you not fashion replacements out of wood or metal to make this issue go away?
