3:1 (3 parts honey to 1 part water) is richer than 2:1 - it has a greater percentage of honey, so it should be the opposite of what I think you're suggesting.
I'm a Bourbon guy so I went with a BIB (Bottled In Bond) Bourbon. The citrus sourness was a bit much. I tried it again with 1/3 oz//10 ml lemon juice and it was definitely more balanced and the Bourbon came through better. You definitely need a stronger Bourbon to overcome the citrus component.
I really can't get over the fact that this drink wasn't "invented" until the 2000s. I mean the very first thought I had when I learned how to make a whiskey sour was "I'll bet this would taste even better with honey instead of simple syrup" honey and lemon just work so well together.
