| Any of those would work, including the Mittel. If it sounds good, use it!
What you have on now -- Anima E and Garbo A is a good choice. Eudoxas are fine strings, very expensive though and not very stable tuning wise. I find Olives and Eudoxas to be almost too dark sometimes. Plain gut has a kind of snap and brightness of its own. Pirastro Pizzicato is a semi-flatwound gut core string that's brighter, lots of $$ though.
My personal affordable favorite is Super Sensitive Sensicore. They are somewhat like Obligato and Evah Pirazzi (two other possibliities) with a synthetic core. Next to them I like Velvets. Innovation 140s, or Super Silvers aren't too bad either. |
