I had a few pads and traces lift from those boards. I wouldn't attribute it
to the lighter copper entirely or necessarily. My first guess is the board
material played some part in it, too. Digikey also sells 1 oz. copper on
FR4, $6 for 6x9 (I think). In my statistically insignificant experience, I
had problems with traces on the Pular boards but no problems with the "good
stuff".
