For those of you that fish dry - dropper rigs, any recommendations on what dries you've had success with over the years?

I'm looking for attractor patterns that are bouyant enough to float a tungsten beadhead nymph for a reasonable amount of time. Back East I've had days when they'd hit an Elk Hair Caddis and not touch a Humpy and out west I've had fish take a Chubby Chernobyl and stay away from a Bugmeister, but I'm sure there will be days when the reverse is true.

As I plan on trying to fish more dry - dropper rigs this year, I'd like to have ready several attractor patterns that I can try depending on various conditions, locations, time of year, hatches, etc.

Thanks.
