RE: Some Streamlined related....
I agree a one-piece-single-metal machinated upper cup-Euro pin part will be better than a two-metallic-three-pieces assembly. Forging or soldering is bad because failure usually occurs precisely at the junction between 2 parts...
I don't use any Locklite or Never-Seize stuff. Just strong tightening of the 2 screws on each interconnecting axis.
I just make sure all the screws on my gear are tight before each session (footstraps, fin, boom head and mast base/tendon/pin assembly).
