Hi Michel,
As far as I am aware the only difference between 50/50 and 60/40 is the lead and tin ratio and therefore the melting temperature is different also the strength.
Yes a wire without rosin core is preferred, over here in Australia I found buying plain lead solder very expensive compared to buying normal cored or electronics solder.
When I got the solder bar from the hardware shop it wasn't really cheap but then I thought it would be a life times supply for me, the same apply's to the flux I got it is the smallest tub they had but still more than enough for a lifetime and not really cheap though not all that expensive either.
I watched Paul's video several times pausing and rewinding to get the details right.
Cheers,
Stephen.
