Welcome from the SF Bay Area. Sounds like you've had a great start. My first briar was an unfinished Savinelli Lumberman, and it's my probably my favorite pipe to smoke, but the bowl is really large.
Sounds like you enjoy some of the darker, stouter flakes. So do I. If you like ODF, I really recommend it's brother blend, Bold Kentucky, which has a bit more dark-fired Kentucky, and a bit less flavoring. If you haven't had any of the strong Gawith, Hogarth & Co. blends, they're also worth a try when in stock. I'm particularly partial to Dark Flake Unscented.
