I have had various success with different variants. I dont know enough to say which ones to be honest.
I had an old school case CB, that didnt fit, I had an ultimate CB from the cartel that didnt fit, but a couple of cheaper ones did. Hence why I got the 203 (this is a mega crap version but it had the CB, it was mineral but was visually better than feel) which did. I was told by a dealer he could source fiddies from 5 different factories so I guess its pot luck.
D will know better than me.
