I use them as well. Usually #1 on top with a #2 or #4 behind. Sometimes for Skagit winters I'll use a #1/0 up top with a #2 in the stinger position. About 20% of the time I use a corkie in the middle. I almost always use Gamagatsu's and I tie em close also. Usually the eye of the stinger hook is right at the point where the top hooks bend is. I also face them in opposite directions. I usually use Maxima Ultragreen 10 or 12 pound but have also tied using 8 or 10 pound Seaguar fluorocarbon depending on environmental factors.

As far as fishing them goes I almost always hook fish with the stinger hook and have yet to loose one this way. Even very large 20+ pounders stay put on the #2.
