Steve, I'm more mandolin/tenor banjo and it fits easily on them but I'm pretty much single melody and wouldn't find a chordal accompaniment I like - another of my own limitations...

As for boxes, I still own a battered Honer Erica. I had a brief spell with a Morris side before Irish sessions became my preferred area (not that when I do get out, I might not try other folk things). I would not get St Anne's to speed on a box - Winster Gallop is more my level. Sometimes I toy with the idea of a (heaven forbid B/C) "Irish Baube" or maybe find out about an old Paulo Soprani... in my dreams, I'd play anything on them but down to earth I think I have to settle for doing as best I can on fretted strings...
