I use streamers often, mostly size 2 4x hooks with a cone head weight. I fish them with a 9 foot 6 weight rod, which is great for those flies. On occasion, I use a size 2 or larger double bunny, and the 6 weight is really not enough rod to cast these flies if you are going to do it often (though it works and I'll still do it, I don't use those flies often enough to take another rod just for them). A 7 or 8 weight is better suited to the larger double bunnies and similar weighted flies.
