Who knows... I haven't seen those around here yet, ours are not pre-tinned.
I don't know what the fuss is about anyway, soldering copper fittings is  
so dead easy with just plain wire and a tin of "soldering paste" (the flux  
only not the one with tin inside). I never understood why they even found  
it necessary to invent the solder bearing paste, and i certainly don't see  
the need for pre-tinned parts. But i guess plumbers charge so much these  
days they have grown lazy of cleaning the copper before soldering. Well, i  
sure don't need one of them anyway...

Won't be long and the copper plumbing will be gone. They make everything  
plastic (PP) now around here, which is directly welded together. I don't  
trust that crimped nonsense, and welding is fairly easy.


About your trial with the pastes, i reckon i might be curious about the  
results, so don't forget to report in a few years time ;-)
