I'm having a reunion with my viola at the moment, and really liking it.

After the first day or so wondering how something this big can be manageable it all seems ok, just the occasional hiccup when I don't know what note/string/finger to play and my C clef head has a moment. The violin is suddenly tiny and squeaky! (Although I love it really

)
I could do with ideas for some repertoire I can look at; something suitable for a more or less beginner violist but fairly experienced violinist. Are there any good violin/viola duets people can recommend? Or even for 2 violas?
