I've read in a few places here and there that there seems to be some concerns with the post Vulfix Duke 3 in Best but I haven't heard concerns with the post Vulfix Chubby 1 I don't know much about the Simpson brush history and subsequent acquisition by Vulfix but I read up on Simpson brushes a little and ordered a Duke 3 in best from WCS last night. Could someone shed some light on this? For example, have problems/issues/inconsistencies been observed with the post Vulfix Duke 3 while the post Vulfix Chubby has been problem free? Just trying to get a better understanding....
