Hello, hello, I'm here!
I agree with whatever sink line Juro recommends, afterall, he visits the darkside more often than I do.
I have used the 8wt 3M Mastery Floating Steelhead Taper for my poppers and am currently using the Bonefish Taper. I also have a friend who throws his poppers with the Bass Bug Taper.
Keep in mind, you're usually throwing weighted flies, or wind-resistant poppers on long leaders in the wind.
I have a slower Scott that I use so I don't overline.
Hope this helps,
