I changed these strings to my early german made 1900 violin, and it lost all brightness from its voice. Voice became soft and somewhat blurred. I changed them into very bright ones, which were then too bright; very metallic voice. So optimal would be somewhere between them. Nice learning experience though; there is difference in strings. Next time I consult professional about which strings should I use. Maybe E-could be softer anyway, but G should be brighter or something...
My Roth Master violin then has mixed set of spares currently(I have changed string by string when cut), and it plays just well, so maybe some violins are not so sensitive on string characteristics.
