I have a rubber net I use for trout. The fish don't get scraped up by the knots and rough filament when you use rubber and my hooks haven't got caught in it. A plus when using one in the saltwater, say at, Sekiu you can net all your fish and keep them in the water to check to see if they are wild or hatchery. Much more fish friendly.
