Yes ESP RRS went up 100% on the AIM when it listed, I happened to be on that ride with RRSO, As you said RRS is more traded on the AIM than on the ASX as the majority of shares are there now.
At least the poms know how to value a coy and they will see the value with CCC and i expect the same returns if not more when it lists on the AIM as CCC is far more attractive than RRS.
