I’ve been checking in and want to say thanks for the input from all, it helps me check what I do against others much more experienced with Hammond products! I’m getting a wonderful growl out of the stock 122 Amp, but have tried some different heads in between the organ plug and the Leslie and that produces even more focused distortion tones so I find my self cleaning up the sound of the Source and the Leslie amp and having most of the distortion brought in by the Amp head plugin in between. The Leslie starts to growl pretty good at a little over half on the Gain Knob for me, but can get way dirtier for other uses that I don’t do in my working group, only when I sit in with the Hard rock gods around here. I have been impressed by the T-racks version but must admit the Amplitude version has a nicer GUI and it looks like more options for the dough. Is it just me or does the new version of VB3 II sound better than the previous, I am curious if it really just the same and my brain makes it sound better or if G mad some improvements other than the Spin plugin part of it. Thanks for any feedback 
Dave
