Well, to answer my own question, I tried the 3 they had at Wunjo’s in Denmark St yesterday, and walked out with one. I was very impressed, sounded beautiful, and the weight, feel, sound and build quality were very consistent between the three.
Also a shout out to the excellent and patient service at Wunjo, even on a busy saturday. They currently have the Casady fretless at £649, which is cheaper than anywhere else I can see.
