As part of my last TAD until at least the new year (if not longer), I decided to try McClelland Matured Virginia Navy Cavendish.
EDIT: I corrected the title of the tobacco. Thanks troutface.
I think you may be confusing two different tobaccos. Navy Cavendish does not have a number designation. It's part of the same series but has the rum topping. So far I have not detected a big rum flavor, but I am still airing out the tin I bought a couple weeks ago, so two bowls is not a lot to give much of an impression.
It was one of the first VAs I ever tried (because it was on the shelf at the local). I remember not really getting it at first, but I remember it finally having a nice, medium VA taste with just a little bit of "tang" to it. I don't remember it being as vinegary as the other McClelland VAs, either. Maybe that's from the rum. Overall, it was definitely a pretty good, medium VA, but I didn't have the ability to appreciate it at the time. It's one I'd like to revisit at some point.
I have a 2 year old tin that I recently opened. I haven't made up my mind about it yet. It's very high quality tobacco for sure, but Va's have to grow on me. I'm pretty sure I'll end up really liking it though!
