While on a quest to find the PERFECT Basil Gimlet recipe, I conducted a couple of side-by-side experiments to find the one that yields a beautifully balanced cocktail. This is it. I recommend following it to the letter, with the one exception being adding more basil than called for. I tried this with Beefeater Lemon Ginger gin - non-starter, and again with Aviation, Nope! I'd stick with a London Dry.
