I have been looking for a new float line and i will pick one up when they are available if they are a large drop from the exorbitant Riffe prices. I had a vinyl floatline that I loved but it got tore up on the coral, and was pretty much unsalvageable.
Marco, you are probably right about the cost and efficiency of the thinner floatlines, but I much prefer a thicker, less knot and tangle prone set-up. Just the other week I had a little scare when my polypro floatline wrapped around my leg and got snagged on a coral head as I was dealing with a fish in the mouth of a cave. Judging from your awesome photos it looks like you do more bluewater, which a thinner float may be better for.
Edit- I like the red.
