Great choices! If you enjoy Ennerdale you'll enjoy every Lakeland tobacco thrown your way, and as Zurg said above, Grousemoor is definitely lemongrass-esque and different enough from the Lady E that it's its own beast.

As you found, it can be tough to get ahold of GH&Co. tobaccos at times and moreso if you start buying in bulk. You'll wait months for some of their ropes to appear in stock, and sometimes almost as long for their regular tobaccos. Thankfully if you enjoy one it's not a stretch to say that you'll enjoy another, so you usually don't have to go without completely.
