Hey guys, Have any of you checked out this site>? http://www.protubeflysystem.com/ As near as I can tell so far it is only available in europe, but the site says it will soon be available in Canada and the US. I think the components that make up this system are very intriguing. I am not so impressed by the propellers, but the different cones, and injection molded tube shapes look like the have some real potential!! At least some of the tubes have pinholes in the sides, for a riffling hitch. Pretty cool. John ps. I had posted this on spey pages, but I thought you guys might be interested too.
