Thank you.
Yes i see it, i seems to be a quality product...by the way i didn't find some reviews of these products.

Mechanicaly speaking i am asking what will happen in the main/helper linking?
During drop phases i am not sure that the helper will have enough "force" to re-aligned the main spring.
See Fe1rx Graph.
That is why the Orb ball joint which is located between Main & Helper seems better to me (i am not sure by the way).
If the GC articulating perche is really smooth (-->low friction, so force to moove it) i think it will be OK.
Is it a nylon ball joint?
otherwise these GC articulating perches may not be compatible with helpers?
For more compliance i really wanted to use helpers, so that is why i ask many questions
& Sorry for my poor english speaking, it is not easy to explain mechanical topics , and it is more difficult when it is not in his first language.
