Greetings Fellow Weirdo! I have maximally enjoyed several Lakelands "essence"/tonquinny blends as well over recent years. Ennerdale was also my entré, which I seriously enjoyed. That led me to try 1792 Flake and Bracken Flake, BOTH of which were HUGE HEAVY HITTERs of the genre, IMHO, which I also enjoyed to the max. They don't make Bracken anymore, or at least it's disappeared from US catalogs. 1792 would be a very logical next step. Grousemoor is something I find entirely different than the tonquin thing. I've read "lemon grass"/herbal to describe. I'm right in the middle of a tin(my first) of Grousemoor as we speak, having spent a couple lovely hours last evening smoking it away in pure pleasure. I honestly don't know how to describe the whole thing... the tobacco is the brightest, lightest yellow I've ever seen in a pipe tobacco. The tin note, also bizarre... like lemon furniture polish, or better yet 200pf limoncello with a touch of acetone, super-sweet/sour penny-candy, and the favorite caustic beverage of the OITMON Nebula pod people. I find the taste/smoking aroma of the tobacco to be almost dissociated from the tin-note. It starts as burning cotton candy, morphs to very pleasantly toasting marshmallows over a camp fire, to baking shoo-fly pie and molasses, to a very calm, very pure fine tobacco taste, like some rich, aged Virginias on xanax. I do plan on always having some Grousemoor on hand.
The only buggabooulous fly in the ointment from my perspective has been that Ennerdale, 1792, and Bracken all totally, utterly, and imperiously not just ghosted, but poltergiested any pipe I smoked them in... almost beyond help. I didn't know this going into the fray, and would have seriously designated A Singular Pipe, just for those blends. At the time, I was not awash in pipes (making progress) so other favorite English/Balkans, VaPers, and others that I did NOT want tainted with The Essence, were seriously impaired. (Of course, one just needs to then buy more pipes... the argument didn't wash with Her Majesty though.)
Also one last quick thought, Hearth & Home used to have a "Lakeland Brickle" that I did not much care for at all... I found it to be so far from the SG and G&H galaxies as to be wholly different and not therefore, scratching the itch, as it were. But always happy different strokes for different folks!
I wish you well with a toast to the tonquin and also congrats for being brave and owning the wierdness! Peace!
