Thanks for the respond.
Don't think that is the problem though, a while back I drill two hole (top and bottom) on a sacrificial bottom housing in order to observe just what is causing the double clicking, but of the many double clicking switches I've tested none had their spring caught onto the switchplate and is operating like how they should normally; plus if that's the case then the clicking should be present when I linear modded them, which is not in my case.
The only postulation I have is that the click leaf, for some reason, resets harder than they should be and thus hitting on the slider (instead of on the housing like when pressed) harder than normally and creating a secondary clicking, I've tried lubing the leaf and the surface of slider that is facing the click leaf (with GPL105) and while this fixed the double clicking initially, they come back once the lube settled in (roughly a week after I lubed it).
Also, is SKBM Whites' click leaf more tactile than Blue Alps' or are they more or less similar in term of tactility?
