I agree midnight biker. Usually i let newbs use my dragon when they play with me, so they dont lose any drives over water. THe ones that bought discs of their own all use the dragon as their main driver. They love it bc its light and will float thru the air pretty well even with a weak drive, and not too overstable. Plus the worryfree floating aspect.
Several of the discs in my bag float, but they all have specific purposes other than floating disc, and the floating is kindof a bonus. Thus, I use them when the situation calls for it. Most of the dloating ones have never even landed in water, since I just haven't had a water shot that they were the right disc for. My putter floats, fortunately, since its gotten wet many-a time, but my tomahawk disc and overstable midrange do as well (Arrow, Epic, and #3 Hookshot, if you were curious), and this hasnt even been a factor. Actually, I lost my Epic today ON LAND while trying to tomahawk out of the MN forest, so floating isnt everything. I just have a good retriever, so I can pull my regulars out of the water in a pinch.
On that note, justin, not to rain on your parade, but the Golden Retriever stinks. It barely touches the surface of the bottom, so if your disc went in at an angle, or sunk into the mucky bottom at all, it will go right over it. Mine is heavier, and shaped like a grappling hook/claw thing, or Robsta Craw as I call it. Some guy named Toad welds them himself in AZ, and I bought it for the same price that golden triangle cost online. Def put its durability to the test, and its rock solid. If you are ever in AZ, i'd recommend you find him at Vista Del Camino and get one. He usually has a couple in the back of his truck.
So, in summary:
Good Retriever > any kind of Floating Disc
(in most situations)
