I'm still extremely happy with the sound of B5 played through real Leslie's. With the new version of UVI workstation I again investigated the audio pops that happen when the B5 GUI is open. Turns out the audio pops only occur in Reaper (and Cubase as I read on another forum) and not with the stand alone UVI application. Arno is aware of this but nothing he can do for these CPU heavy actions. Fortunately it does not happen when the GUI is closed and as I have it mapped perfectly to my XK-3c it's really not an issue. Would love to try Blue3 but B5 is the only B3 VST that maps to the XK-3C.
