I say good work to be looking in this direction.
I don't like leather scents so I won't comment on them.
I've tried all of the Truefitt and Hill scents. I like Trafalgar (spicey wood) and also Grafton (dusky green). West Indian Limes is a classic, very citrus-y.
I've tried most of the Geo F. Trumper line. I like Marlborough, Astor (both spicy woods), and Curzon (dusky green).
