Other hops you might choose would be Amarillo, Citra, and Mandarina Bavaria. Those have a higher alpha acid content and give off citrus aromas. I get grapefruit from Citra and mild tangerine notes from the Mandarina hop. These hops are generally a bit more potent than Lemondrop on the bitterness scale.
The Lemondrop bittering in Founders Solid Gold is around 20IBU which is about 1.5x what you'll find in a typical light American lager with the same alcohol and gravity level. It's well-balanced and a good example of how the hop works in a lighter beer.
