Your tastes may evolve. I use a 1:1:1 ratio now and it's probably my favourite cocktail. I even liberally interpret the Garabaldi and use Campari with any orange drink I fancy. It's amazing how a first impression can change. At first I absolutely did push the gin higher to temper the bitterness - I think it's better that everyone start that way instead of falling into the trap of replacing the Campari with something much weaker.
