Keep in mind I’ve only had a couple bowls out of a fresh tin of Gillingham, but it striked me as similar to Winchester but with more Cavendish.
I, like you, wanted a non-aro or lightly aromatic cavendish although I approached it as wanting a softer smoke. I tried straight Cavendish and that didn’t suit me, too boring. Winchester fits the bill for me but my curiosity will lead me to try other “Cavendish but not too much” type blends. I also want to play with adding C&D unflavored cavendish to blends. I hope you enjoy your search!
