I used a 10 wt last year at the PINS trip, outfitted with an intermediate sinking line. I used Scientific Anglers "Bonefish" line; it did the trick really well. I liked the sink rate and depth - not too deep which was right for the surf. I had a stripping basket with me, but quickly left it on the beach as it was unnecessary with the intermediate sinking line. I've not tried a floating line, but I would think you'd fight it unless the surf was dead calm.
When you're ready to try it out give me a call!
