Have you tried the version with the 3/4oz split of rye vermouth cognac and 1/4oz Benedictine with 14 drops each of Peychauds and angostura? I can’t recall where I saw that but it balances quite well
I really enjoy this spec which for me the rum split is 1oz smith and cross 3/4oz plantation oftd and 3/4oz Bacardi ocho. I also really enjoy 1oz plantation 5, 3/4 oz plantation oftd or Hamilton 151, 3/4oz lemon hart 1804. I did make your previous spec with 1 2/3oz smith and cross and 3/4oz plantation 3 star and was very happy with. The jet pilot is just such a classic recipe which allows a creative mixer room to truly experience rum
