Glad it's working out for you. I've been using a Caravel for a few months (sourced from the very good folk at OE) and am astonished at the flavour it can deliver. I've had my best results using a Macap grinder at the same setting that I would use for my Elektra Semi. I haven't yet managed to duplicate those results with a handgrinder (results have mostly been crema-less, thin, and nasty) but because the Caravel is in my office I haven't had enough opportunity to get the handgrinders dialed in. Work can be a pain that way. I'm encouraged by your results with the Leinhartz.
